Your assessment of pointwise operators in MATLAB is incorrect. The
pointwise operators in MATLAB are used heavily to vectorise the scalar
operations, exactly the same as what you describe in numpy. Recently,
the MATLAB JIT has become good enough that looping is fast, however,
the pointwise operators remain "the MATLAB way" of programming.
