基于MATLAB的窗函数法设计FIR数字滤波器

function varargout = unt3(varargin) % UNT3 MATLAB code for unt3.fig % UNT3, by itself, creates a new UNT3 or raises the existing % singleton*. % % H = UNT3 returns the handle to a new UNT3 or the handle to % the existing singleton*. % % UNT3('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in UNT3.M with the given input arguments. % % UNT3('Property','Value',...) creates a new UNT3 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before unt3_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to unt3_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
