`which `

displays
the full path for `item`

`item`

.

If

`item`

is a MATLAB^{®}function in a MATLAB code file (`.m`

,`.mlx`

, or`.p`

extension), or a Simulink^{®}model (`.slx`

or`.mdl`

extension), then`which`

displays the full path for the corresponding file.`item`

must be on the MATLAB path.If

`item`

is a method in a loaded Java^{®}class, then`which`

displays the package, class, and method name for that method.If

`item`

is a workspace variable, then`which`

displays a message identifying`item`

as a variable.If

`item`

is a file name including the extension, and it is in the current working folder or on the MATLAB path, then`which`

displays the full path of`item`

.

If `item`

is an overloaded function or method,
then `which`

`item`

returns only
the path of the first function or method found.

`which ___ -all`

displays the
paths to all items on the MATLAB path with the requested name.
Such items include methods of instantiated classes. You can use `-all`

with
the input arguments of any of the previous syntaxes.

When the class is not loaded,

`which`

only finds methods if they are defined in separate files in an @-folder and are not in any packages.
