built-in functions used in polyval

How can I find out which built in functions does polyval uses? (or any other for that matter)

Answer 1

[John D'Errico]

matlab.codetools.requiredFilesAndProducts('polyval')
ans = 
     {}

Or,

type polyval

which is safer than edit, since you cannot accidentally edit the code and create a bug.

Thank you John but "type" isn't exactly what i'm looking for. I wasn't clear on my question. Is there a way to get a list of all these functions that are being used from an other function(like polyval)? I mean you can see them manually if you "type polyval", but is there a way to get a list of them?

[Steven Lord]

How would you use such a list once you've generated it?

Answer 2

[TastyPastry]

Command window -> edit polyval

Answer 3

[Walter Roberson]

You can use the profiler when you run polyval.

However, profiler tends not to list MATLAB built-in functions. Remember that nearly all calculation on MATLAB involves calling functions: see http://uk.mathworks.com/matlabcentral/answers/38787-what-can-be-programmed-without-any-built-in-functions
