I understand that you want to create a matrix ABCD with 4 complex vectors A, B, C and D. Based on the code snippet you posted, it appears that the admittance parameters 'y_params' are available. Using the function 'y2abcd', you are able to convert the admittance parameters y_params into the ABCD-parameters abcd_params.
For information about this function, please refer to the following link:
