[Getfem-users] Sparse U in getfem::interpolator_on_mesh_fem(mf, U)

[Torquil Macdonald Sørensen]

Hi!

I'm interested in using

getfem::interpolator_on_mesh_fem(const mesh_fem &mf, const 
std::vector<scalar_type> &U),

but I will use it for functions that are very localised, i.e. have only 
very few nonzero components in U. Wouldn't it be an advantage if this 
function would accept sparse arrays instead of only std::vector? Since 
I'm used to sparse arrays in getfem++, I am wondering if there is a 
particular reason that this function only accepts dense arrays?

Best regards
