Hi all, I was wondering what are the possibilities to do a product element by element between a matrix A (m rows ,n columns)and a vector (let say column vector v (m elements) ): I want each element of each column of A to be multiplied by each element of v at the same row. What I'm using for now is a product by a diagonal matrix based on v. For large matrix in data manipulation (typ. 100000 rows), it's necessary to use sparse to allocate better the diag matrix otherwise it's out of memory for usual machine. So i'm using --> diag(sparse(v)) * A
Have you best practise to share on this topic ?
