87 column vector with the same number of rows as M) to scale rows of 87 column vector with the same number of rows as M) to scale rows of
88 M by elements of v. Similarly, if w is a row vector with as many 88 M by elements of v. Similarly, if w is a row vector with as many
89 columns as M, then either w .* M or M .* w scales the columns of 89 columns as M, then either w .* M or M .* w scales the columns of

92 * Given two vectors x and y of length m and n, implement a function
93 outer (x, y, f) that returns an m-by-n matrix with entries
94 f (x(i), y(j)). If f is omitted, multiplication is the default.
