MatUseScaledForm
For matrix storage formats that scale the matrix (for example MPIRowBS matrices are diagonally scaled on assembly) indicates matrix operations (MatMult() etc) are applied using the scaled matrix.
Synopsis

Collective on Mat
Input Parameter

|
scaled | - PETSC_TRUE for applying the scaled, PETSC_FALSE for
applying the original matrix
|
Notes
For scaled matrix formats, applying the original, unscaled matrix
will be slightly more expensive
