【滤波器】基于 FIR实现高通+低通+带通+带阻滤波器设计含Matlab源码

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