TaoGetJacobianEqualityRoutine

Gets the function used to compute equality constraint Jacobian.

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoGetJacobianEqualityRoutine(Tao tao, Mat *J, Mat *Jpre, PetscErrorCode (**func)(Tao tao, Vec x, Mat J, Mat Jpre, void *ctx), void **ctx)

Not Collective

Input Parameter

• tao - the Tao context

Output Parameters

• J - the matrix to internally hold the constraint computation

• Jpre - the matrix used to construct the preconditioner

• func - Jacobian evaluation routine

• ctx - the (optional) user-defined context

Calling sequence of func

• tao - the Tao context

• x - input vector

• J - Jacobian matrix

• Jpre - matrix used to construct the preconditioner, usually the same as J

• ctx - [optional] user-defined Jacobian context
