    In your videos you refer to 'previous videos' and 'next videos' without naming them. It would be helpful if you numbered the videos and referred to them explicitly by name and number. It would enhance understanding if the verbal definitions of time delays and feedback delays were accompanied by illustrative examples.

    I have a question: In a previous video you demonstrated ways of creating the input and target data in various lags in Excell. Here, in this code if we specify the input delay as 1:5, do we need to prepare the input in Excell with lag 1. lag 2..lag 5 arranged in adjacent columns or Matlab is clever enough to generate that on its one from a simple time series?

      annual oscillation refers to the yearly cyclic events which occurs in either the whole atmosphere or a climate variable . one of the example is season changes. whereas semi annual oscillation are the changes obeserved twice a year and one of the example is change in trade winds (west to east and east to west)
