Fixed-Point Basics in Simulink

Fixed-point number representation, scaling, range, precision, arithmetic operations

To assign a fixed-point data type to a signal or block in Simulink®, construct a Simulink.NumericType object using the fixdt function. You can use the Fixed-Point Tool to automatically assign fixed-point data types to objects in your model based on collected range information.
