Complexity of output ports

returns whether each output port has complex data. The number of outputs must match the

For System objects with one input and one output and where you want the input and output
complexities to be the same, you do not need to implement this method. In this case
isOutputComplexImpl assumes the input and output
complexities are the same and returns the complexity of the input.
If your System object has more than one input or output or you need the output and input
complexities to be different, you must implement the
isOutputComplexImpl method to define the output complexity. You also must
propagatedInputComplexity method if the output
complexity differs from the input complexity.
During Simulink® model compilation and propagation, the MATLAB System block calls the
isOutputComplex method, which then calls the
isOutputComplexImpl method to determine the output
