I have a time series and a (complex) frequency response function .
I want to compute the time history obtained applying to in the frequency domain.
Does matlab has a high-level function to do this without having to code all the transformations to and from the frequency domain myself?

You can do this easily in Simulink. Create a model of H(f) using the transfer function block. Load your input in workspace and pass if to the transfer function model in Simulink through an input port. Save the output of transfer function again to workspace. Should work without any issue.


I need to do this inside a bigger piece of code and I have never used simulink.
Is there a way to do it inside a script?
