Optimize Generated Code for Complex Signals

This example shows how Simulink Coder handles complex signals efficiently. To view the data types of the signals, update the model using Simulation > Update Diagram. Complex signals are represented as structures in generated code. Simulink Coder performs various optimizations on these structures. For example:

  • Expression Folding: Gain and Sum operations on the complex signal are folded into a single expression.
  • For-loop fusion: Two separate for-loops, one for the complex signal and one for noncomplex signal, are combined into a single for-loop.
  • Inlined block parameters: The value of Gain block "pi" is inlined in the expression of the complex Gain-Sum.

Because of optimizations such as these, the code generated for complex and noncomplex signals is equally efficient.
