Ron,

what's the point of using Transpose? doesn't the array have the same
dimension even without transposing?


Yes, but you need to multiply each element in each array by the other; if you don't transpose then you will only do a one-to-one, rather than a one-to-all. Like multiplying two arrays of columns, vs an array of row by an array of columns.
