Hello everyone, I am just wondering whether there is a function doing the opposite of MatSetValuesStencil. I tried to find a MatGetValues equivalent for using structured grid indexing, but it seems that MatGetValuesStencil does not exist.
I have a sparse matrix A built on DMDA. If I want to use A's entries to build another DMDA matrices B, what is the best way to retrieve A's entries? Is it possible to use grid indexing? Thank you. Best, Xiangdong
