On balance, I've met people who claim they are intermediate programmers and use matlab only, and are freaked to shit when they see higher order functions in other languages, or even the idea of passing a "function", like, say, a pointer to a function, into another function, even though function pointers have existed since C.
They exist in Matlab too. They're called function handles. Matlab has functionalish functions like `arrayfun`, `cellfun` (akin to `map`) or `accumarray` (akin to `fold`), but the Matlab documentation prefers to teach loops, presumably because they're easier to understand, and usually faster in Matlab thanks to their JIT compiler.
I'm surprised that people are so surprised that you can pass function handles around, since there are some Matlab functions for solving ODEs or root-finding that are very commonly taught in intro courses that require function handles. I guess not everyone's first exposure to Matlab involves solving ODEs or root-finding.
