Re: [Getfem-users] Question about Hadamard product

[Renard Yves]

Dear Kayhan,

The Hadamard vector product is not implemented in gmm. Of course it  
should not be difficult to implement it at least for dense vectors. It  
is similar to a sum of two vectors. The interface with the blas  
routines (SHAD, DHAD, CHAD and ZHAD) can be made also similarly to the  
sum of to dense vector (see gmm_blas_interface.h).


Yves.
