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 Many br

Input Parameters

comm - MPI communicator, set to PETSC_COMM_SELF Many br
m - number of rows Many br
n - number of columns Many br
data - optional location of matrix data in column major order. Set data=NULL for PETSc Many brto control all matrix memory allocation. Many br

Output Parameter

A -the matrix Many br

Notes

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