MatFDColoringGetFrequency
Gets the frequency for computing new Jacobian matrices.
Synopsis
int MatFDColoringGetFrequency(MatFDColoring matfd,int *freq)
Not
Collective
Input Parameters
coloring -the coloring context
Output Parameters
freq -frequency (default is 1)
Notes
Using a modified Newton strategy, where the Jacobian remains fixed for
severaliterations, can be cost effective in terms of overall nonlinear
solutionefficiency. This parameter indicates that a new Jacobian will be computed
every<freq> nonlinear iterations.
