[petsc-users] Mat-Mat element wise multiplication

[Rui Silva]

I am writing to you, to ask if there is any simple way to perform 
element-wise multiplication of 2 mpiaij matrices in Petsc? Furthermore 
is there any way to reassemble a matrix that has some zeros stored, to 
reduce the sparsity of the matrix?

Thanks a lot in advance,

R
