TestUniform

public static void TestUniform(double[] yo,
 double to,
 double tf,
 double h,
 IDerivative deriv,
 IStopper stopper,
 IRkListener listener,
 double[] answer)

Test the uniform step size

Parameters:

yo - initial values. Probably something like (xo, yo, zo, vxo, vyo, vzo).

to - the initial value of the independent variable, e.g., time.

tf - the maximum value of the independent variable.

deriv - the derivative computer (interface). This is where the problem specificity resides.

stopper - if not null will be used to exit the integration early because some condition has been reached.

listener - listens for each step

answer -

test

public static void test()

main

public static void main(String[] arg)
