Details:

I have the following case where rectint is giving an incorrect result:


octave> rectint ([0 0 5 5], [6 6 5 5])
ans = 0
octave> rectint ([0 0 5 5], [6 0 5 5])
ans = 0
octave> rectint ([0 0 5 5], [0 6 5 5])
ans =  5


This should be 0 in all cases. The logic of the function is a bit convoluted
but I already have a complete rewrite that fixes this and adds support for N
dimensions. (this gives me a bug number to use on the commit message :p)
