gradient

void gradient(int mTotalConstraints,
 int mEqualityConstraints,
 double[] x,
 boolean[] active,
 double f,
 double[] g,
 double[] df,
 double[][] dg)

Deprecated.

Computes the value of the gradient of the function at the given point.

Parameters:

mTotalConstraints - an input int value specifying the total number of constraints.

mEqualityConstraints - an input int value specyfying the number of equality constraints

x - an input double array, the point at which the function is to be evaluated

active - an input boolean array, specifying the active constraints

f - an input double, the value of the function at x

g - an input double array containing the values of the constraints at point x.

df - an output doublearray containing the values of the gradient of the objective function at x

dg - an output MMAX by N double array containing the values of the gradients for the active constraints. MMAX is the maximum of 1 and mTotalConstraints. N is the number of variables.
