what - List MATLAB^® files in current directory

Graphical Interface

As an alternative to the what function, use the Current Directory Browser. To open it, select Current Directory from the Desktop menu in the MATLAB desktop.

Syntax

what what dirname what class s = what('dirname')

Description

what lists the M, MAT, MEX, MDL, and P-files and the class directories that reside in the current working directory.

what dirname lists the files in directory dirname on the MATLAB search path. It is not necessary to enter the full pathname of the directory. The last component, or last two components, is sufficient.

what class lists the files in method directory, @class. For example, what cfit lists the MATLAB files in toolbox/curvefit/curvefit/@cfit.

s = what('dirname') returns the results in a structure array with these fields.

Field	Description
`path`	Path to directory
`m`	Cell array of M-file names
`mat`	Cell array of MAT-file names
`mex`	Cell array of MEX-file names
`mdl`	Cell array of MDL-file names
`p`	Cell array of P-file names
`classes`	Cell array of class directories

Examples

List the files in toolbox/matlab/audiovideo:

Obtain a structure array containing the MATLAB filenames in toolbox/matlab/general:

s = what('general')
s = 
       path: 'matlabroot:\toolbox\matlab\general'
          m: {89x1 cell}
        mat: {0x1 cell}
        mex: {2x1 cell}
        mdl: {0x1 cell}
          p: {'callgraphviz.p'}
    classes: {'char'}
   packages: {0x1 cell}
