Hi,Does anyone have an example of using the ident() function in PETScMatrix. I cannot get it to work and using a for loop with set() to create an identity matrix is painfully slow...
This is how I do it now: Matrix A; A.init(n,n,1); for (int i=0; i<n; ++i) A.set(i,i,1); and it kills me/my computer. Kind regards, Jesper
