Hi rooters,
I have a small problem with the reading of a TMatrix object stored in a
file.
//example.C
{
f = new TFile("th232.root");
f->ls();
accordeon->Print();
for(int i=0;i<5;i++) {
cout << accordeon(i,0) << endl;}
}
When I run the example I have a segmentation violation but I don't
understand why.
root [0] .x exeample.C
TFile** th232.root HBOOK file: th232.hbook converted to ROOT
TFile* th232.root HBOOK file: th232.hbook converted to ROOT
KEY: TMatrix accordeon;1 Accordeon used for the run
Matrix 5x2 is as follows
| 0 | 1 |
------------------------------------------------------------------
0 | 1024 1
1 | 1024 1
2 | 1024 1
3 | 1024 1
4 | 1024 1
1024
*** Break *** segmentation violation

If I run it again it works ! What is wrong ?
