Copy. if nargin == 2 % if the number of inputs equals 2. z = 5 % then make the third value, z, equal to my default value, 5. end. Now if I only input x and y, the function will still run with a default value of z as z=5. By default, MATLAB stores the number as the smallest unsigned integer type that can accommodate it. However, you can use an optional suffix to specify the type of integer that stores the value. ... (larger than flintmax) using int64, precision can be lost because MATLAB initially represents a numeric array input as double precision by default ...Without the subtype field, the conversion characters %o, %x, %X, and %u treat input data as integers. To treat input data as floating-point values instead and convert them to octal, decimal, or hexadecimal representations, use one of following subtype specifiers.
