Re: Support for 8 bit integers

Thank you for the reply, but it is really the 8x
memory  that is my problem. When working with images
sequences (video) you quickly use a lot of memory.
Multiplying the memory requirements with 8 just makes
the problem 8 times more serious.

As a sidenote, if Octave supported "true" integers
then MMX instructions could be used and thereby gain a
lot of speed.
