Hello Madhan ravi,

following is the picture of model. In this simulink model I am trying to run above algorithm, for first iteration I need to give some input as shown in above script. in tx,ty,....data will be stored after all iteration. It is working matlab (script) but not in simulink. My mail id is dpawanpawar@gmail.com. Is that possible to contact you.
