% SPECWIN spectral window object class constructor. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % DESCRIPTION: SPECWIN spectral window object class constructor. % Create a spectral window from libSpecWin. % % SUPERCLASSES: ltpda_nuo < ltpda_obj % % SPECWIN CONSTRUCTORS: % % w = specwin() - creates an empty object % w = specwin(w) - copies a specwin object % w = specwin('name') - creates the specified specwin object % w = specwin('name', N) - creates a specwin object of a % particular type and length. % w = specwin('Kaiser', N, psll) - create a specwin Kaiser window % with the prescribed psll. % % 'name' should be one of the following standard windows: % % Rectangular, Welch, Bartlett, Hanning, Hamming, % Nuttall3, Nuttall4, Nuttall3a, Nuttall3b, Nuttall4a % Nuttall4b, Nuttall4c, BH92, SFT3F, SFT3M, FTNI, SFT4F, SFT5F % SFT4M, FTHP, HFT70, FTSRS, SFT5M, HFT90D, HFT95, HFT116D % HFT144D, HFT169D, HFT196D, HFT223D, HFT248D % % VERSION: $Id: specwin.m,v 1.80 2011/05/24 16:19:00 mauro Exp $ % % SEE ALSO: ltpda_obj, ltpda_nuo % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% classdef (Hidden = true) specwin < ltpda_nuo %------------------------------------------------ %---------- Private read-only Properties -------- %------------------------------------------------ properties (SetAccess = private) type = '';
