Input in matlab

MATLAB preserves the “Not a Number” status of alternate NaN representations and treats all of the different representations of NaN equivalently. However, in some special cases (perhaps due to hardware limitations), MATLAB does not preserve the exact bit pattern of alternate NaN representations throughout an entire calculation, and instead uses the canonical NaN bit pattern defined above.

Example: The input arguments ('%*.*f',6,4,pi,9,6,exp(1)) return '3.1416 2.718282', with 9 and 6 as the field width and precision for the output of exp(1).
