Pulse signal analysis based on MATLAB GUI

Pulse signal analysis based on MATLAB GUI

Pulse signal analysis is one of the important research directions in the medical field, which can provide key information about the functional status of the cardiovascular system. In this article, we will introduce how to use MATLAB's GUI tool for pulse signal analysis. We will show how to plot pulse waveforms, calculate metrics such as pulse rate and pulse pressure, and provide the corresponding source code.

First, we need to create a MATLAB GUI application. Enter the command in the MATLAB command window guideand select the "Blank GUI" template to create a new GUI application.

Next, we need to design the user interface of the GUI. In the GUI designer, we can add various controls, such as buttons, text boxes, drawing areas, etc. The following is a simple example interface design:

function varargout = PulseAnalysisGUI(varargin)
% GUI初始化函数

% 设置默认值
defaultBackgroundColor = [0.94, 0.94, 0.94]; % 设置背景颜色

% 创建GUI主窗口
fig = figure('Visible','off',...
             'Position',[360,500,450,285],...
             'Color', defaultBackgroundColor);

% 创建按钮
pushbutton = uicontrol('Style','pushbutton',...
                       'String','分析',...
                       'Position',[315,220,70,25],...
                       'Callback',@analyzeButton_Callback);

% 创建文本框
