At the top of the screenshot we can see a detailed explanation about the usage of ismembc
and its sibling function ismembc2. Unfortunately, internal helper functions are seldom
documented: we often need to use educated guesses and trial-and-errors.
The next step is guring out the inputs to the internal function. In this case, either via
simple static code inspection or by step-by-step debugging, we easily conclude that these
are the same two inputs sent to the wrapper function ismember.
We next check whether the internal function is on the path. Luckily, it is in this case:*
