MatCreateSeqDense#

Creates a MATSEQDENSE 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

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

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.
