Hi. This is the help page for matlab about what their call (in matlab slang) the "vectorization process", instead of the use of "scalar approach" which include for and while loops: https://la.mathworks.com/help/matlab/matlab_prog/vectorization.html

So, scalar = for, while, slow, and vectorial = vectorize in smath, and fast.

Best regards

Alvaro.
