gradient

void gradient(double[] x,
              double[] g)

Public interface for the user-supplied function to compute the gradient at point x.

Parameters:

x - a double array, the point at which the gradient is evaluated. x.length equals the number of variables.

g - a double array, the values of the gradient of the objective function.
