MatMPIDenseSetPreallocation#

Sets the array used to store the matrix entries

Synopsis#

Collective

Input Parameters#

  • B - the matrix

  • data - optional location of matrix data. Set to NULL for PETSc to control all matrix memory allocation.

Notes#

The dense format is fully compatible with standard Fortran storage by columns.

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