Here I am playing with some Julia code. My favorite Julia. Don’t tell Sarah. Sarah source code needs a complete overhaul.

Interesting aspects of Julia, parenthesis are for functions, square brackets are for indexing. This is a biggie when translating from other languages. The human, not the machine, has to decide
is this a function with two arguments or a matrix with two indices, or a vector with one argument.
