Re: Passing Large Arrays to Function

[Max Görner]

Octave does copy on write. So passing variables anywhere does not
duplicate it, be it an assignment or a passing to a function. Only right
before the first change the variable gets duplicated.

So you can pass that big value as often as you want to if you don't
change it. This might not be as good as having references, but it's
quite decent anyway. You could try that using a very simple recursion.

BTW: Does Octave notice that it can operate on the passed arguments
directly? Matlab states to notice that in

   var = foo(var)

the variable 'var' can be manipulated directly, thus saving speed and
memory.

sincerly
