set.m

基于matlab的面向对象的信号处理类库。主要应用于音频、语音信号的一些处理。内含简单的使用说明

function a = set(a,varargin)
% SET Set signal properties and return the updated object
%
%    A=SET(A,prop1,val1,prop2,val2,...) sets properties to their
%    respective values. Allowed properties are:
%
%      time
%      s
%      fs
%      valid
