C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™.Jan 1, 2018 · MATLAB "is" functions also return logical arrays that indicate which elements of the input meet a certain condition. For example, check which elements of a string vector are missing using the ismissing function. 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.
