dec2base is a nice function but slow for large arrays and quite RAM hungry.
This version is a lot faster and minimizes RAM usage. It has the same input-output behavior as dec2base.

To make use of this improvement, just replace all your dec2base calls with ndec2base.

Included are two files: ndec2base.m and fdec2base.m

ndec2base has the same error checks as dec2base
fdec2base skips error checks to be a little faster, is only faster on small arrays

Function is fastest for bases 10 and lower.

For best results call the function on a whole array instead of calling it on each element.
