rc_filter.m

计算RC（阻容）滤波时间常数的程序

function varargout = RC_filter(varargin)
% RC_FILTER M-file for RC_filter.fig
%      RC_FILTER, by itself, creates a new RC_FILTER or raises the existing
%      singleton*.
%
%      H = RC_FILTER returns the handle to a new RC_FILTER or the handle to
%      the existing singleton*.
%
%      RC_FILTER('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in RC_FILTER.M with the given input arguments.
%
%      RC_FILTER('Property','Value',...) creates a new RC_FILTER or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before RC_filter_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to RC_filter_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
