Member Function Documentation

AddAt()

void TArrayD::AddAt	(	Double_t	c,
		Int_t	i
	)

Set the double c value at position i in the array.

Check for out of bounds. Warning: the name of the method is misleading, it actually overwrites the position i.

Definition at line 94 of file TArrayD.cxx.

Adopt()

void TArrayD::Adopt	(	Int_t	n,
		Double_t *	arr
	)

Adopt array arr into TArrayD, i.e.

don't copy arr but use it directly in TArrayD. User may not delete arr, TArrayD dtor will do it.
