# TaoComputeJacobian

Computes the Jacobian matrix that has been set.

## Synopsis

    #include "tao_solver.h"
    int TaoComputeJacobian(TAO_SOLVER solver,TaoVec* xx,TaoMat *JJ)

Collective on TAO_SOLVER and Mat

## Input Parameters

| solver | - the TAO_SOLVER solver context
| xx | - input vector

## Output Parameters

| JJ | - Jacobian matrix

## Notes

TaoComputeJacobian() is typically used within minimization implementations, so most users would not generally call this routine themselves.

## Keywords
