MatCreateSeqDense
Creates a sequential dense matrix that is stored in column major order (the usual Fortran 77 manner). Many of the matrix operations use the BLAS and LAPACK routines.
Synopsis
#include "petscmat.h"
PetscErrorCode MatCreateSeqDense(MPI_Comm comm,PetscInt m,PetscInt n,PetscScalar *data,Mat *A)
Collective on MPI_Comm
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. Set data=NULL for PETSc
to control all matrix memory allocation.
|
Output Parameter
A -the matrix
Notes
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.
