In the second case you might want to consider using spmd . The reason parfor is slower than a for loop for short ranges or fast itera...

The regular composition works for unary functions. In the case of binary, we can define (f .: g) x y = f (g x y) -- which is also = f ((g x) y) = (f . g x) y -- by definition of (.) = (f .) (g x) y = ((f .) . g) x y Thus,...
