c1 - the function result at 1.0.

Method Detail

getN

public double getN()

Returns the interpolation exponent. The default value is 1.

Returns:

The interpolation exponent.

setN

public void setN(double n)

Sets the interpolation exponent.

Parameters:

n - the new interpolation exponent.

getC0

public float[] getC0()
