Documentation

Hamming window class. Hamming is a generalized Hamming window class. The classic Hamming window is Wm(x) = 0.54 - 0.46*cos(x). This is generalized to Wm(x) = beta - (1-beta)*cos(x) where beta can take any value in the range 0<beta<1. Beta=0.5 corresponds to the Hannig window.

Hamming(void)

Default constructor. Use the true hamming window parameter, beta=0.54.

explicit Hamming(int len, double mBeta=0.54)

Full constructor. Construct a generalized Hamming window of length 'len'. If beta isn't specified it defalts to the true hamming window.
