    %UINT16 Convert to unsigned 16-bit integer.
%   I = UINT16(X) converts the elements of the array X into unsigned 16-bit
%   integers. X can be any numeric object, such as a DOUBLE. The values
%   of a UINT16 range from 0 to 65535, or INTMIN('uint16') to INTMAX('uint16').
%   Values outside this range saturate on overflow, namely they are mapped
%   to 0 or 65535 if they are outside the range. If X is already an unsigned
%   16-bit integer array, then UINT16 has no effect. DOUBLE and SINGLE values
%   are rounded to the nearest UINT16 value on conversion.
%
%   Some arithmetic operations are defined for UINT16 on interaction with
%   other UINT16 arrays. For example, +, -, .*, ./, .\ and .^.
%   If at least one operand is scalar, *, /, \ and ^ are also defined.
%   UINT16 arrays may also interact with scalar DOUBLE variables, including
%   constants, and the result of the operation is UINT16.
%   UINT16 arrays saturate on overflow in arithmetic.
%
%   You can define or overload your own methods for the UINT16 class (as you
%   can for any object) by placing the appropriately named method in an
%   @uint16 directory within a directory on your path.
%   Type HELP DATATYPES for the names of the methods you can overload.
%
%   A particularly efficient way to initialize a large UINT16 arrays is: 
%
%      I = zeros(1000,1000,'uint16')
%
%   which creates a 1000x1000 element UINT16 array, all of whose entries are
%   zero. You can also use ONES and EYE in a similar manner.
%
%   Example:
%      X = 17 * ones(5,6,'uint16')
