#include "petscmat.h" #include "petscts.h" int TSDefaultComputeJacobianColor(TS ts,PetscReal t,Vec x1,Mat *J,Mat *B,MatStructure *flag,void *ctx)Collective on TS, Vec and Mat
ts | - nonlinear solver object | |
t | - current time | |
x1 | - location at which to evaluate Jacobian | |
ctx | - coloring context, where ctx must have type MatFDColoring, as created via MatFDColoringCreate() |
J | - Jacobian matrix (not altered in this routine) | |
B | - newly computed Jacobian matrix to use with preconditioner (generally the same as J) | |
flag | - flag indicating whether the matrix sparsity structure has changed |
-mat_fd_coloring_freq <freq>
