If you convert aNaNvalue to an integer class, the result is a value of0in that integer class. For example: int32(NaN) ans = int32 0 Arithmetic Operations on Integer Classes MATLAB can perform integer arithmetic on the following types of data: ...
Both linspace and the : operator create row vectors. However, you can convert a row vector into a column vector using the transpose operator ('). >> x = 1:3; >> x = x' x = 1 2 3 Transpose x from a row vector to a column vector using the transpose operator. ...
