Get Slepian Tapers
Return a matrix of Slepian tapers
get.slepians(npoints = 900, nwin = 5, npi = 3)
npoints |
Number of points to return |
nwin |
Number of windows (default =5) |
npi |
Pi-Prolate numerber (3) |
This function onlyu returns the tapers for inspection. To apply the tapers use the function mtapspec.
