Constructor Details

SwimZRange

public SwimZRange(double zo,
 double zf,
 double stepSize)

Create an integration range

Parameters:

zo - the staring value

zf - the ending value

stepSize - the approximate stepsize. It will be modified to the next smaller stepsize that requires an integer number of steps.

Method Details

getZo

public double getZo()

Get the starting value of z

Returns:

the starting value of z

getZf

public double getZf()

Get the final value of z

Returns:

the final value of z

getNumStep

public int getNumStep()

Get the number of steps

Returns:

the number of steps

getSetpSize

public double getSetpSize()

Get the step size. This is the first stepsize smaller than the one provided in the constructor that ensures an integer number of steps takes us exactly to zf, i.e. zf = zo + numStep*stepSize

Returns:

the step size in Z

z

public double z(int n)

Obtain z for a given step number n [0, numStep]

Parameters:

n - the value of n

Returns:

the z value

main

public static void main(String[] arg)
