How can I determine which functions in a MATLAB file originate from a specific toolbox?

How can I determine which function originated the use of a MATLAB toolbox in my code files? 

For example, I produce the following code in a script titled "Test.m":

dp = 300; wavelen = 3;
sp = dop2speed(dp,wavelen);

Then I execute the following:

>> [fList, pList] = matlab.codetools.requiredFilesAndProducts('Test.m')
>> plist(1,2).Name
ans = 
'Phased Array System Toolbox'

Calling "matlab.codetools.requiredFilesAndProducts" reports the toolboxes that are used but not the functions belonging to the toolboxes. How can I find out which function in my code is from 'Phased Array System Toolbox'?

In order to determine the function that originates the use of a toolbox, you should generate a Dependency Report. This report identifies the toolboxes being used and the MATLAB functions files belonging to the toolboxes.

When a dependency report is generated on the script it will produce the following line:

Test             | toolbox             :  \phased\phased\dop2speed.m

This indicates that the "dop2speed.m" function used in the MATLAB file "Test.m" originated from the Phased Array System Toolbox.
