MatReuse

Indicates if matrices obtained from a previous call to MatCreateSubMatrices(), MatCreateSubMatrix(), MatConvert() or several other functions are to be reused to store the new matrix values.

Synopsis

typedef enum {
  MAT_INITIAL_MATRIX,
  MAT_REUSE_MATRIX,
  MAT_IGNORE_MATRIX,
  MAT_INPLACE_MATRIX
} MatReuse;

MAT_INITIAL_MATRIX - create a new matrix

MAT_REUSE_MATRIX - reuse the matrix created with a previous call that used MAT_INITIAL_MATRIX

MAT_INPLACE_MATRIX - replace the first input matrix with the new matrix (not applicable to all functions)

MAT_IGNORE_MATRIX - do not create a new matrix or reuse a give matrix, just ignore that matrix argument (not applicable to all functions)

Any additions/changes here MUST also be made in include/petsc/finclude/petscmat.h
