【信号去噪】基于小波变换、中值滤波多种算法实现心电信号预处理含Matlab源码

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