Complexity of output ports
[cp_1,cp_2,...,cp_n] = isOutputComplexImpl(obj)
[cp_1,cp_2,...,cp_n] = isOutputComplexImpl(obj) returns whether each output port has complex data. The number of outputs must match the value returned from the getNumOutputs method or the number of output arguments listed in the step method.
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 use the 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 complexity.
Logical, scalar value indicating whether the specific output port is complex (true) or real (false).
