Method Detail

hessian

void hessian(double[] x,
             double[][] hess)

Public interface for the Hessian of the multivariate function to be minimized.

Parameters:

x - a double array, the point at which the Hessian of the function is to be evaluated

hess - a double matrix, the value of the Hessian of the function at x
