% FSDATA frequency-series object class constructor. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % DESCRIPTION: FSDATA frequency-series object class constructor. % Create a frequency-series data object. % % SUPER CLASSES: data2D < ltpda_data < ltpda_nuo < ltpda_obj % % CONSTRUCTORS: % % fsd = fsdata() - creates a blank frequency-series object % fsd = fsdata(y) - creates a frequency-series object with the given % y-data. Sample rate of the data is assumed to % be 1Hz. % fsd = fsdata(f,y) - creates a frequency-series object with the given % (x,y)-data. The sample rate is then set as % 2*x(end). % fsd = fsdata(y,fs) - creates a frequency-series object with the given % y-data and sample rate. The frequency % vector is grown assuming the first y % sample corresponds to 0Hz and the last % sample corresponds to the Nyquist % frequency. % fsd = fsdata(x,y,fs) - creates a frequency-series object with the given % x,y-data and sample rate. % % VERSION: $Id: fsdata.m,v 1.62 2011/03/30 13:17:33 mauro Exp $ % % SEE ALSO: tsdata, fsdata, xydata, cdata, data2D, data3D, xyzdata % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% classdef (Hidden = true) fsdata < data2D %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Property definition % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %---------- Public (read/write) Properties ---------- properties end %---------- Protected read-only Properties ---------- properties (GetAccess = public, SetAccess = protected) t0 = time(0);
