Method Detail

jacobian

void jacobian(double[] x,
              double[][] jac)

Returns the value of the Jacobian at the given point.

Parameters:

x - a double array of length n 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 n by n 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].
