Hello! Madhan,

I am trying to convert a model from continuous to discrete and I used >> c2d(ASAS_Model,0.1,'zoh'); but I got errror on converting to discrete: Please find the below the error.

>> c2d(ASAS_Model,0.1,'zoh');

Error using c2d (line 57)

The A matrix must be square.

Could you please give us feedback about this issue. Thanks!
