RAND syntax

[Eyal Doron]

Hi John,

   I noticed that the syntax of "rand" seems to be out of date. It is the
old syntax of Matlab 3.5, rather than the new syntax of Matlab 4.x,
and indeed of the rest of Octave. Thus,

octave:6> ones([2 2])
ans =

  1  1
  1  1

octave:7> rand([2,2])
ans =

  -1.83413  -0.83267

(its on "normal"), so that "rand(size(A))" does not work as expected.

I suggest this be fixed. Also, I suggest adding a "randn" function, to
enhance Matlab 4.x compatibility.
