But it's not "practically every function". It's hardly any function at

consider it an error for function(42) and function([42]) to behave the
same way. One is a scalar, and the other is a vector -- they're different
things, it's poor programming practice to treat them identically.
(If Matlab does this, so much the worse for Matlab, in my opinion.)
There's actually good reason to do this in heavily matrix-oriented
specialized languages; there are numerous applications where scalars and
1x1 matrices are mathematically equivalent.
