Let's say I have a function defined as :

function output = mainFunction(input1, input2)
  a=calledFunction1(input1,input2);
  b=calledFunction2(input1);
  output= a + b ;
end

Is there a way to get the name of the functions that are called inside the mainFunction ? Such that it would return something like :

calledFunctions(mainFunction)
ans =
    calledFunction1
    calledFunction2

I did not find any existing function that does it.

Because function references can constructed from strings at run time, probably the best way is to use the profiler.

There used to be depfun (or was it dfun), which has been replaced by a long command string that is difficult to remember

Thank you. Actually, using profiler in this way

profile on
mainFunction
p=profile('info');

and then accessing

p.FunctionTable.FunctionName

gives the expected result.
