John,

There is no bicubic function as such in matlab, as it is part of the 
interp1 function, etc. So I'm not sure that this code is a copyright 
infringement of mathworks.... I suspect that the author is just very 
heavily influenced by matlab help syntax.. In any case given that I 
think its probably worth clarifying that no mathworks code was used in 
the development of this function. So your question should still be 
answered..

Cheers
David
