class TMatrixTSparse< Element >

TMatrixTSparse.

Template class of a general sparse matrix in the Harwell-Boeing format

Besides the usual shape/size descriptors of a matrix like fNrows, fRowLwb,fNcols and fColLwb, we also store a row index, fRowIndex and column index, fColIndex only for those elements unequal zero:

fRowIndex[0,..,fNrows]:    Stores for each row the index range of
                           the elements in the data and column array
fColIndex[0,..,fNelems-1]: Stores the column number for each data
                           element != 0

As an example how to access all sparse data elements:

TMatrixTSparse<double> M;
auto rowIndex = M.GetRowIndexArray();
auto colIndex = M.GetColIndexArray();
auto matrix = M.GetMatrixArray();
for (Int_t irow = 0; irow < M.GetNrows(); irow++) {
  const Int_t sIndex = rowIndex[irow];
  const Int_t eIndex = rowIndex[irow+1];
  for (Int_t index = sIndex; index < eIndex; index++) {
    const Int_t icol = colIndex[index];
    const double data = matrix[index];
    printf("data(%d,%d) = %.4e\n", irow + M.GetRowLwb(), icol +  M.GetColLwb(), data);
  }
}

When checking whether sparse matrices are compatible (like in an assignment !), not only the shape parameters are compared but also the sparse structure through fRowIndex and fColIndex .

Several methods exist to fill a sparse matrix with data entries. Most are the same like for dense matrices but some care has to be taken with regard to performance. In the constructor, always the shape of the matrix has to be specified in some form . Data can be entered through the following methods :

1. constructor from COO matrix format

   TMatrixTSparse(Int_t row_lwb,Int_t row_upb,Int_t dol_lwb,
                  Int_t col_upb,Int_t nr_nonzeros,
                  Int_t *row, Int_t *col,Element *data);

   It uses SetMatrixArray(..), see below
2. constructor from Harwell-Boeing (CSR) matrix format

   TMatrixTSparse(Int_t row_lwb,Int_t row_upb,Int_t dol_lwb,
                  Int_t col_upb,
                  Int_t *rowptr, Int_t *col,Element *data);

   It copies input arrays into matrix .
3. copy constructors
4. SetMatrixArray(Int_t nr,Int_t *irow,Int_t *icol,Element *data) where it is expected that the irow,icol and data array contain nr entries . Only the entries with non-zero data[i] value are inserted. Be aware that the input data array will be modified inside the routine for doing the necessary sorting of indices !
5. SetMatrixArray(Int_t nr,Int_t nrows,Int_t ncols,Int_t *irow, Int_t *icol,Element *data) where it is expected that the irow, icol and data array contain nr entries . It allows to reshape the matrix according to nrows and ncols. Only the entries with non-zero data[i] value are inserted. Be aware that the input data array will be modified inside the routine for doing the necessary sorting of indices !
6. TMatrixTSparse a(n,m); for(....) { a(i,j) = .... This is a very flexible method but expensive :
   • if no entry for slot (i,j) is found in the sparse index table it will be entered, which involves some memory management !
   • before invoking this method in a loop it is smart to first set the index table through a call to SetSparseIndex(..)
7. SetSub(Int_t row_lwb,Int_t col_lwb,const TMatrixTBase &source) the matrix to be inserted at position (row_lwb,col_lwb) can be both dense or sparse .

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

		Int_t	col_lwb,
		Int_t	col_upb,
		Int_t	nr,
		Int_t *	row,
		Int_t *	col,
		Element *	data )

Space is allocated for row/column indices and data.

Sparse row/column index structure together with data is coming from the arrays, row, col and data, resp. Here row, col and data are arrays of length nr (number of nonzero elements), i.e. the matrix is stored in COO (coordinate) format. Note that the input arrays are not passed as const since they will be modified !

		Int_t	col_upb,
		Int_t *	rowptr,
		Int_t *	col,
		Element *	data )

Space is allocated for row/column indices and data.

Sparsity pattern is given by column indices and row pointers from arrays col and rowptr, resp, while matrix entries come from the array data. Arrays col and data are assumed to have length nr (number of nonzero elements), while array rowptr has length (n+1), where n=row_upb-row_lwb+1 is the number of rows.

Definition at line 362 of file TMatrixTBase.cxx.

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

CheckedHash()

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Paint()

void TObject::Paint ( Option_t * option = "" )

virtualinherited

This method must be overridden if a class wants to paint itself.

The difference between Paint() and Draw() is that when a object draws itself it is added to the display list of the pad in which it is drawn (and automatically redrawn whenever the pad is redrawn). While paint just draws the object without adding it to the pad display list.

SaveAs()

void TObject::SaveAs ( const char * filename = "", Option_t * option = "" ) const

virtualinherited

Save this object in the file specified by filename.

• if "filename" contains ".root" the object is saved in filename as root binary file.
• if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
• if "filename" contains ".cc" the object is saved in filename as C code independent from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().

• otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

  The function is available via the object context menu.

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
