UINT64 UINT64 Convert to Unsigned 64-bit Integer

Usage

Converts the argument to an unsigned 64-bit Integer.  The syntax
for its use is

   y = uint64(x)

where x is an n-dimensional numerical array.  Conversion
follows the general C rules (e.g., if x is outside the normal
range for an unsigned 64-bit integer of [0,2^64-1], the least 
significant 64 bits of x are used after conversion to an integer).  
Note that both NaN and Inf both map to 0.
