1 %WHICH Locate functions and files.
2 % WHICH ITEM displays the full path for ITEM. ITEM can include a partial
3 % path, complete path, relative path, or no path. ITEM must be on the
4 % search path or in the current folder.
5 %
6 % If ITEM is a Simulink model, a MATLAB app file, or a MATLAB function or
7 % script in a MATLAB code file, then WHICH displays the full path for the
8 % corresponding file.
9 %
10 % If ITEM is a method in a loaded Java class, then WHICH displays the
11 % package, class, and method name for that method.
12 %
13 % If ITEM is a workspace variable, then WHICH displays a message
14 % identifying ITEM as a variable.
15 %
16 % If ITEM is a file name with a specified extension, then WHICH displays
17 % the full path of ITEM.
18 %
19 % If ITEM is an overloaded function or method, then WHICH ITEM returns
20 % only the path of the first function or method found.
21 %
22 % WHICH FUN1 in FUN2 displays the path to function FUN1 that is called by
23 % file FUN2. Use this syntax to determine whether a local function is
24 % being called instead of a function on the path. This syntax does not
25 % locate nested functions.
26 %
27 % WHICH ___ -ALL displays the paths to all items on the MATLAB path with
28 % the requested name. Such items include methods of instantiated classes.
29 % You can use -ALL with the input arguments of any of the previous
30 % syntaxes.
31 %
32 % S = WHICH(ITEM) returns the full path for ITEM in the character vector, S.
33 %
34 % S = WHICH(FUN1,'IN',FUN2) returns the path to function FUN1 that is
35 % called by file FUN2. Use this syntax to determine whether a local
36 % function is being called instead of a function on the path. This syntax
37 % does not locate nested functions.
38 %
39 % S = WHICH(___,'-ALL') returns the results of WHICH in the character vector or
40 % cell array of character vectors, S. You can use this syntax with any of the input
41 % arguments in the previous syntax group. Each row of cell array S
42 % identifies a function. The functions are in order of precedence, unless
43 % they are shadowed. Among shadowed functions, you should not rely on the
44 % order of the functions in S.
45 %
46 % For more information about function precedence order, see the MATLAB
47 % documentation.
