MatCreateDenseWithMemType

Create a matrix that matches the supplied PetscMemType.

Synopsis

#include "petscmat.h"   
PetscErrorCode MatCreateDenseWithMemType(MPI_Comm comm, PetscMemType mtype, PetscInt m, PetscInt n, PetscInt M, PetscInt N, PetscInt lda, PetscScalar *data, Mat *A)

Collective

Input Parameters

• comm - the communicator

• mtype - the memory type

• m - number of local rows (or PETSC_DECIDE to have calculated if M is given)

• n - number of local columns (or PETSC_DECIDE to have calculated if N is given)

• M - number of global rows (or PETSC_DECIDE to have calculated if m is given)

• N - number of global columns (or PETSC_DECIDE to have calculated if n is given)

• lda - leading dimension (or PETSC_DECIDE to use the default)

• data - optional location of matrix data, which should match the specified mtype. Pass NULL to have PETSc take care of matrix memory allocation.

Output Parameter

• A - the dense matrix
