MatCreateSeqDense

Creates a MATSEQDENSE that is stored in column major order (the usual Fortran format).

Synopsis

#include "petscmat.h" 
PetscErrorCode MatCreateSeqDense(MPI_Comm comm, PetscInt m, PetscInt n, PetscScalar data[], Mat *A)

Collective

Input Parameters

• comm - MPI communicator, set to PETSC_COMM_SELF

• m - number of rows

• n - number of columns

• data - optional location of matrix data in column major order. Use NULL for PETSc to control all matrix memory allocation.

Output Parameter

• A - the matrix

Note

The data input variable is intended primarily for Fortran programmers who wish to allocate their own matrix memory space. Most users should set data = NULL.

Developer Note

Many of the matrix operations for this variant use the BLAS and LAPACK routines.
