Hello,
You may refer to the Matlab component’s datasheet in OptiSystem for more information about using it. You need to make sure that the signal structure is chosen correctly after you set the inputs and output of the Matlab component. Then you write your code in Matlab to manipulate the signal. The output signal of the Matlab component will be passed to OptiSystem and continue propagation in the other components.
We need to get valid maintenance and support license to fully support you.
regards,
Ahmad
