I understand that you want to run the simulation multiple times for different values of gate-source voltage (Vgs). For some reasons, you are not able to get the expected output.
I simulated the Simulink model attached by you and was able to reproduce the issue. I am suggesting some small changes to be made in the code attached by you in the “Codice.m” file. They are as follows:
- The output of the “sim” command should be saved in a variable “out”
- Use “hold on” command to hold previous plots on the same figure.
- Use proper commands to show legends in the plot.
I have also attached the modified MAT file. I executed it and found it to be working properly. The below given figure shows the plot of “Vds” vs “Ids” for Vgs=[4 5] generated by running the code “Codice.m”
I hope it answers your question!
