As a complement, I took time to prepare a sample programms of how I handle
multi-dimensionnal array in my everyday code. It compares it to a classic
pointer access.<br />I'll be glad to discuss results of such methods on
different platform and discuss pros and cons of this method.<br /><br />On
most platform, whener the data fits in the cache, both methods ends up in
a few tenth of percent of margin. For larger array, the difference grows
but it can be diminished by using loop tiling or loop blocking. Moreover
the natural [][] syntax eases the way you can write complex element acces
patterns.
