Is there a Way to Determine Which Function Will be Called Without Actually Calling the Function ?
显示 更早的评论
Suppose there is a function myfunc that has many instantiations on the path because of overloading. Is there a way to determine which instantion will be called based on the form of the function call without actually calling the function? For example, supppose I have x and y in my workspace. Is there something like this:
which myfunc(x,y)
that returns the full path to the myfunc that would be executed, but doesn't actually call myfunc?

Yes, and in fact you've already given the syntax for that call! See the "Locate Function Invoked with Given Input Arguments" example on the documentation page for the which function.
>> syms x
>> which sin(x)
C:\Program Files\MATLAB\R2020a\toolbox\symbolic\symbolic\@sym\sin.m % sym method
Though since you use the word "return" you'd need to use the function form of which with an output argument.
>> N = which('sin(x)')

Use
which -all myfunc
Also, try running the attached script.
