## Industry Cases of Reading MAT Files in MATLAB: Exploring Applications Across Various Sectors for Expanding Perspectives

# 1. The Basics of Reading MAT Files in MATLAB

MATLAB is a programming language widely used for technical computing and data analysis. A MAT file is a binary file format used in MATLAB to store data and variables. This chapter will introduce the basics of reading MAT files in MATLAB, including:

- **MAT File Format:** A MAT file is a binary format used to store MATLAB variables, data structures, and objects. It employs a proprietary format readable only by MATLAB or compatible software.
- **load Function:** The load function is the primary function in MATLAB for reading MAT files. It can load an entire MAT file or selectively load specific variables.
- **Variable Selection:** When using the load function, variables can be selected by specifying variable names or using wildcards.
