Octave equivalent of Matlab's rand??

[Julien Martin]

Hello,

1. I would like to know what is the Octave equivalent of Matlab's "rand" keyword (look at line 2 and note that there are no parentheses).

Here is my program:
function X=GenereVariable(p1, p2, Delta1, Delta2)
U = rand;
X=Delta1 * (U<=p1) - Delta2 * (p1<U) * (p1+p2 >=U);
end

2. Is there a website that references all Octave/Matlab incompatibilities/differences? If so can anyone please direct me to it?

Thanks in advance,
Julien.
