int SNESDefaultComputeJacobianWithColoring(SNES snes,Vec x1,Mat *J,Mat *B, MatStructure *flag,void *ctx)Collective on SNES
snes | - nonlinear solver object |
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 |
