MATLAB as (Near-)PseudoCode

In "Teaching Data Science in English (Not in Math)", the Feb-08-2016 entry of his Web log, "The Datatist", Charles Givre criticizes the use of specialized math symbols (capital sigma for summation, etc.) and Greek letters as being confusing, especially to newcomers to the field. He suggests that "English" (pseudo-code) be used instead, such as the following: Although there are some flaws in this particular comparison (1. the first example includes an unnecessary middle portion, 2. it also features the linear model definition, while the pseudo-code example does not, and 3. the indexing variable in the summation is straightforward in this case, but is not always so), I tend to agree. Despite my own familiarity with the math jargon, I agree with him that, in many cases, pseudo-code is easier to understand. Pseudo-code is certainly simpler syntactically since it tends to make heavy use of (sometimes deeply-nested) functions, as opposed to floating subscripts, superscripts and baroque symbols. Pseudo-code often employs real names for parameters, variables and constants, as opposed to letters. It is also closer to computer code that one actually writes, which is the point of this post.
