How to use software to create a 1D cascade of two port networks

Please can anyone help with how to use MATLAB or Octave to create a 1D cascade of two port networks to cascade scattering parameters with e.g 100 elements.

Convert your S-parameters to ABCD parameters. The cascade results is then a simple multiplication of the ABCD matrices. Finally, convert the multiplied ABCD result back to S-parameters.

See "Cascade connection" and "ABCD-parameters" here:

Thanks for your kindness.But what am talking about is cascading scattering matrix of many two port networks consisting of different RLCG as elements for each of the two port network, dont you think ABCD matrices would be too tedious?
Thanks for your understanding

Why is it tedious if you add this simple (S) -> ABCD -> (S) conversion to your code? It is the standard way of doing this task.
