Question

I have installed a library that has some functions with the same name as MATLAB’s. And by installing the lib, I mean addpath. When I try to call those function it’ll use that lib’s implementation but I want to call MATLAB implementation.

To make it simpler: how can I specify which function to call given that I have the absolute address of both functions?

I searched for the answer but I didn’t find it on the website.

Answer 1

If you overload any of the MATLAB built-in functions to handle a specific class, then MATLAB always calls the overloaded function on that type. If, for some reason, you need to call the built-in version, you can override the usual calling mechanism using the builtin function. The expression

builtin('reshape', arg1, arg2, ..., argN);

forces a call to the MATLAB built-in function, reshape, passing the arguments shown even though an overload exists for the class in this argument list.
