public void jacobian(double[] x,
double[][] jac)
- Returns the value of the Jacobian at the given point.
- Parameters:
x
- a double
array which contains the point at which
the Jacobian is to be evaluated. The contents of this array
must not be altered by this function.jac
- a double
matrix which contains the value of the
Jacobian at x. The value of jac[i][j] is the derivative
of f[i] with respect to x[j].
