ccosine.m

这是一个基于matlab开发的关于c语言的图形转换程序,可实现直方图的生成和传输

function f = sinusoid(varargin)
%CCOSINE Create a CCOSINE object.
%   f = CCOSINE('Parameter1','Value1','Parameter2','Value2',...)
%   create an object of class 'sinusoid' with the given parameters.
%
%   f = CCOSINE(Signal,'Parameter1','Value1','Parameter2','Value2',...)
%   uses the CCOSINE object Signal as a template.
%
%   This function can be called with no arguments, or just a subset of
%   parameter/value pairs as well.  In that case, default values are substituted.
