Fixed-Point Operator Replacement - MATLAB & Simulink (original) (raw)
Define code replacement mappings for fixed-point operations
Use the Code Replacement Tool or programming interface to define code replacement mappings for fixed-point operations, including shift left operations and different types of scaling — for example, binary point or net slope.
