MATLAB GUI Implementation Code with Four Practical Examples

This MATLAB GUI implementation provides four excellent examples that will help you effectively learn and master relevant GUI development skills. These examples include: 1. Multi-Axes GUI Interface: This example teaches how to control which axes become the target for plotting commands, and implements numeric input processing through edit text boxes. The implementation uses MATLAB's axis handle management and callback functions to switch between different plotting surfaces while validating numerical inputs using str2double conversion. 2. List Box Directory Reader: Through this example, you'll learn path acquisition techniques, file loading procedures, and file opening mechanisms. The code demonstrates using uigetdir/uigetfile functions for directory navigation, populating list boxes with file entries, and implementing double-click callbacks for file access operations. 3. Workspace Variable Access via List Box: This example shows how to retrieve variable names from the base workspace into a list box, enabling multi-selection capabilities. The implementation involves using who/whos functions to get workspace variables, dynamic list population, and handling multiple selections through the list box's Value property. 4. MAT File Operations: This example demonstrates opening, saving, and modifying MAT files using the handles structure for storing and retrieving shared data across GUI components. The code illustrates load/save functions with different parameters, maintains data consistency through the handles guidata mechanism, and implements file modification workflows with proper error handling.
