Thank Mark for your reply.
Could you please check your link. It's not working for me.

I linked ti the topic on this forum "Does yalmip support parallelism of knitro solver?"

My answer there:

Try using

sdpsettings('solver','knitro','knitro.optionsfile',knitro_options_filename)

and set the options you  want in knitro_options_filename .

It worked.

Thank you Mark.

So basically, we create a text file in the same directory as the model and list all the parameters or options we want to pass to the solver in that file. Then, we tell yalmip to pass these options to the solver.

sdpsettings('solver','knitro','knitro.optionsfile','knitro_options_file.txt')
