Method Detail

initialize

public boolean initialize()

Implements the initialize() method in the base class. Initializes member data and prepares for execution of first step. This method "resets" the algorithm.

Specified by:

initialize in class Algorithm

Returns:

returns true if sets of data are valid

checkdata_KF

public boolean checkdata_KF(java.util.Vector<MyPoint> kf)

Validates the class entered by user for Partical Filtering

Parameters:

kf -

Returns:

true if data is Vector kf is valid. It is invalid if the size of kf is 1 or any element is larger than the the previous element

run

public void run()

Implementation of the run function from the Runnable interface. Determines what the current step is and calls the appropriate method.

Specified by:

run in interface java.lang.Runnable

Specified by:

run in class Algorithm

interpol

public void interpol(java.util.Vector<MyPoint> v,
                     java.util.Vector<MyPoint> iset)

Calculates the interpolated points for the data inputs

Parameters:

v - input data points

iset - interpolated data points

spline

public void spline(double[] x,
                   double[] y,
                   double[] y2,
                   int size)

Actually interpolates the points

Parameters:

x - array containing the x coordinates of datapoints

y - array containing the y coordinates of datapoints

y2 - array containing the interpolated y coordinates

size - the size of the array to be interpolated

splint

public void splint(MyPoint u1,
                   MyPoint u2,
                   MyPoint r,
                   double[] y2,
                   int i)

Interpolates for a point between the two known points using Cubic Interpolation

Parameters:

u1 - start point for the interpolation

u2 - end point for the interpolation

r - returning point, basically the interpolated point

y2 - array used for reassigning of r

i - the sample number

mean

public double mean(java.util.Vector<MyPoint> v,
                   java.util.Vector<MyPoint> mv)

Calculates the mean and the zero-mean data points

Parameters:

v - orginal datapoints

mv - zero mean datapoints

Returns:

The average in a double
