The function dpss in the Matlab Signal Processing Tool Box4.10 can be used to compute them as follows:
w = dpss(M,alpha,1); % discrete prolate spheroidal sequencewhere is the desired window length, and can be interpreted as half of the window's time-bandwidth product in ``cycles''. Alternatively, can be interpreted as the highest bin number inside the main lobe of the window transform , when the DFT length is equal to the window length . (See the next section on the Kaiser window for more on this point.)
Some examples of DPSS windows and window transforms are given in Fig.3.29.
