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 CLASSNAME.
CLASSNAME must be either 'single' or 'double'.
