what

List MATLAB files in folder

Syntax

what

what folderName

s = what(___)

Description

what lists the path for the current folder and all the MATLAB^® relevant files and folders in the current folder. Such files and folders include MATLAB program files (.m and .mlx), MAT files, Simulink^® model files (.mdl and .slx), MEX files, MATLAB app files (.mlapp), and P-code files, as well as all class and namespace folders.

what folderName lists path, file, and folder information for folderName. You do not need to specify the @ or + symbol for class and namespace folders. For example, what table lists the MATLAB files and folders in toolbox/matlab/datatypes/@table.

s = what(___) returns the results in a structure array. You can use this syntax with any of the input argument combinations in the previous syntaxes.

Examples

List Path, File, and Folder Information

List the MATLAB files and folders in the graph2d folder. The location of this folder depends on your installation.

Input Arguments

folderName — Name of folder

character vector | string scalar

Name of folder, specified as a character vector or string scalar.

For a local folder, you do not need to specify the full path of the folder. Instead, you can specify a relative partial path. For example, what strfun and what matlab/strfun both list the MATLAB files in toolbox/matlab/strfun. However, if the folder is at a remote location, then folderName must contain a full path specified as a uniform resource locator (URL). For more information, see Work with Remote Data.

The case sensitivity of folderName is determined by your file system. In general, Windows^® and Mac systems are case insensitive and therefore, what returns results for all case variations of folderName. For example, suppose the folder c:\mycode contains the file myfile.m on a Windows file system. what successfully locates the folder even if you specify a different case.

what MYCodE

MATLAB Code files in folder c:\mycode
myfile

On Linux^® systems, which are generally case sensitive, what returns zero results.

Output Arguments

s — List of path, files, and folders
