Method Detail

jacobian

double[][] jacobian(double t,
                    double[] y,
                    double[] yprime)

Used to compute the Jacobian of the function at t.

Parameters:

t - a double, the point at which the function is to be evaluated. (Input)

y - a double array which contains the dependent variable values. (Input)

yprime - a double array which contains the value of the function \( \frac{dy}{dt} = y^{'} = f(t,y) \). (Input)

Returns:

a double y.length by y.length matrix containing the value of the Jacobian of the function at t. (Output)
