TMatrixTLazy!

ROOT
1

Hi,

I’m an amateur in ROOT and know some decent amount of c++ and am trying to make a relatively simple recursive function manipulating TMatrix(ces?). In the TMatrixTBase Doc, it mentions how return matrices are very heavy and recommended to use TMatrixTLazy which is apparent in my code. I’ve been trying to fix the vlazy.cxx (in $ROOTSYS/test/) but it feels… outdated? Otherwise, I cannot find any other examples of it in use.

Cheers!
Stephen

Hi,

How is vlazy.cxx outdated? What are you attempted to fix (i.e. it seems to compile and run as expected).

Cheers,
Philippe.
