%NaN    Not-a-Number.
%   NaN is the IEEE arithmetic representation for Not-a-Number.
%   A NaN is obtained as a result of mathematically undefined
%   operations like 0.0/0.0  and inf-inf.
%
%   NaN('double') is the same as NaN with no inputs.
%
%   NaN('single') is the single precision representation of NaN.
%
%   NaN(N) is an N-by-N matrix of NaNs.
%
%   NaN(M,N) or NaN([M,N]) is an M-by-N matrix of NaNs.
%
%   NaN(M,N,P,...) or NaN([M,N,P,...]) is an M-by-N-by-P-by-... array of NaNs.
%
%   NaN(..., CLASSNAME) is an array of NaNs of class specified by the 
%   string CLASSNAME. CLASSNAME can be either 'single' or 'double'.
%
%   NaN(..., 'like', Y) is an array of NaNs with the same data type, sparsity,
%   and complexity (real or complex) as the single or double precision numeric 
%   variable Y.
%
%   Note: The size inputs M, N, and P... should be nonnegative integers. 
%   Negative integers are treated as 0.
