Method Detail

getPolyDegree

public int getPolyDegree()

The number of degrees a polynomy will have.
Warning:
With more degrees, more adjustment is achieved, however, values greater than 10 can slow the process.

Returns:

int

setPolyDegree

public void setPolyDegree(int value)

Sets the number of degrees a polynomy will have.
Warning:
With more degrees, more adjustment is achieved, however, values greater than 10 can slow the process.

Parameters:

value - int

polyFit

public void polyFit(int numPoints,
                    double[] x,
                    double[] y)

Calculate the polynomial fit

Parameters:

numPoints - int is the number of points to fit

x - double[] x values

y - double[] y values

polyEval

public double polyEval(double x)

Evaluate function by using polyDegree polynomial with polyCoeff at value x.

Parameters:

x - double

Returns:

double
