Creating a Model (Using Simulink)

Using Simulink

Working with Complex Signals

By default, the values of Simulink signals are real numbers. However, models can create and manipulates signals that have complex numbers as values.

You can introduce a complex-valued signal into a model in any of the following ways:

Load complex-valued signal data from the MATLAB workspace into the model via a root-level inport.
Create a Constant block in your model and set its value to a complex number.
Create real signals corresponding to the real and imaginary parts of a complex signal and then combine the parts into a complex signal, using Real-Imag to Complex conversion block.

You can manipulate complex signals via blocks that accept them. Most Simulink blocks accept complex signals as input. If you are not sure whether a block accepts complex signals, refer to the documentation for the block in Chapter 8, "Block Reference."
