Dear all, I used MatCreate() to create a non-square matrix B, and set values to it in parallel. Now i want to get the tranpose of it to solve Ax=B', where A is SeqDense.
I define a SeqDense C=B' and use MatTranspose() to get it, then apply MatMatSolve(fact,C,x), but i get the following error: [0]PETSC ERROR: --------------------- Error Message ------------------------------------ [0]PETSC ERROR: Nonconforming object sizes! [0]PETSC ERROR: Mat A,Mat B: local dim 27 14! [0]PETSC ERROR: ------------------------------------------------------------------------ Thank you in advance, Likun
