It doesn't say they they are minute, because obviously they aren't. The fact alone that numpy has fundamental datatypes which don't exist in MATLAB should be enough to make it functionally distinct.

Seriously please read the article and try to actually use these tools. You would very quickly realize just how different numpys approach is to MATLAB. Again, they don't even operate on the same types. MATLAB only knows the n-dimensional array, that data type doesn't exist in numpy where the array has quite a different fundamental structure, which becomes pretty clear if you read the article.

I get that someone with little experience in both languages might be confused, purely looking from the outside they might seem similar, but if you are familiar with both you realize that they are very different and require you to approach implementations from different directions.

Ultimately numpy was designed to fit into python, which will always limit it compared to a DSL.
