Ok, but it goes against the conventions of octave/matlab in that all

Yes I know that it is against the conventions but I save a lot of memory if
I can operate directly on the input matrix using, for example,


instead of the conventional method, where the results are stored in a new
output matrix,

    Y = myfunc(A);

which requires twice as much memory.
