Method Detail

hamming

public static final double hamming(int piN,
                                   int piLength)

Retrieves a single value of hamming window based on length and index within the window.

Parameters:

piN - index into the window

piLength - the total length of the window

Returns:

the hamming value within the window length; 0 if outside of the window

hamming

public static final void hamming(double[] padWindow)

Applies hamming window to an array of doubles.

Parameters:

padWindow - array of doubles to apply windowing to

Since:

0.2.0

sqrtHamming

public static final double sqrtHamming(int piIndex,
                                       int piSize)

Calculates square root Hamming window value given index and size.

Parameters:

piIndex - window index

piSize - window size

Returns:

resulting squared hamming window

Since:

0.3.0.2
