Hexadecimal and Binary Values

Specify hexadecimal and binary values either as literals or as text. Hexadecimal and binary literals are stored as integers. You can convert text representing hexadecimal and binary values to numbers, and numbers to text representations.

Valid Combinations of Unlike Classes

If you include elements of unlike classes in a matrix, MATLAB® converts some elements so that all elements of the resulting matrix are of the same type. Data type conversion is done with respect to a preset precedence of classes.
