GUI-based TXT File Reading and Saving Application

This application is developed using MATLAB GUI for reading and saving TXT files. During development, we implemented various programming techniques including data structure optimization and algorithm design. The core functionality utilizes MATLAB's file I/O functions (fopen, fscanf, fclose) with efficient buffer management for handling large text files. The GUI components employ callback functions for interactive file selection dialogs (uigetfile) and dynamic text display in edit boxes (uicontrol). The programming approach incorporates error handling mechanisms using try-catch blocks and implements data validation algorithms to ensure file integrity. This project integrates knowledge from multiple disciplines including computer science (file parsing algorithms), mathematics (data formatting calculations), and physics (for potential scientific data processing applications). While these interdisciplinary concepts may present challenges for new learners, systematic study and practical application enable deeper understanding and mastery. Therefore, this program not only helps beginners acquire fundamental programming skills but also expands their perspective towards broader knowledge domains and technical competencies.
