Tips



  • Use frest.findSources to identify time-varying source blocks that can interfere
    with frequency response estimation. To disable such blocks to estimate frequency
    response, set the BlocksToHoldConstant option of frestimateOptions equal to
    blocks or a subset of blocks. Then, estimate the frequency response using
    frestimate.

  • Sometimes, model includes referenced models containing source blocks in the signal
    path of a linearization output point. In such cases, set the referenced models to normal
    simulation mode to ensure that frest.findSources locates them. Use the
    set_param command to set SimulationMode of any referenced models to Normal
    before running frest.FindSources.
