Identify Program Dependencies

If you need to know what other functions and scripts your program is dependent upon,

use one of the techniques described below.

Simple Display of Program File Dependencies

For a simple display of all program files referenced by a particular function, follow these

steps:

1 Type clear functions to clear all functions from memory (see Note below).

Noteclear functions does not clear functions locked by mlock. If you have

locked functions (which you can check using inmem) unlock them with munlock, and

then repeat step 1.

2 Execute the function you want to check. Note that the function arguments you choose

to use in this step are important, because you can get different results when calling

the same function with different arguments.

3 Type inmem to display all program files that were used when the function ran. If you

want to see what MEX-files were used as well, specify an additional output:

[mfiles, mexfiles] = inmem

Detailed Display of Program File Dependencies

For a more detailed display of dependent function information, use the

matlab.codetools.requiredFilesAndProducts function. In addition to program

files, matlab.codetools.requiredFilesAndProducts shows which MathWorks

products a particular function depends on. If you have a function, myFun, that calls to the

edge function in the Image Processing Toolbox™:

[fList,pList] = matlab.codetools.requiredFilesAndProducts('myFun.m');

fList

fList =

'C:\work\myFun.m'

The only required program file, is the function file itself, myFun.
