This article provides an in-depth exploration of methods for recursively obtaining all files under a specific directory in MATLAB. It begins by introducing the basic usage of MATLAB's built-in dir function and its enhanced recursive search capability introduced in R2016b, where the **/*.m pattern conveniently retrieves all .m files across subdirectories. The paper then details the implementation principles of a custom recursive function getAllFiles, which collects all file paths by traversing directory structures, distinguishing files from folders, excluding special directories (. and ..), and recursively calling itself. The article also discusses advanced features of third-party tools like dirPlus.m, including regular expression filtering and custom validation functions, offering solutions for complex file screening needs. Finally, practical code examples demonstrate how to apply these methods in batch file processing scenarios, helping readers choose the most suitable implementation based on specific requirements.
