Hi I'm tring to run a simulink model from M-file using 'sim' command. The simulink model needs some input values, that I'm try to pass from M-file code. But I'm not able to do it. Can anyone help me with this?

I've attached the pictures of M-file code, Simulink Model and error I get.

Your M file can put the data into the base workspace as a variable with a known name. Then your Simulink model can use the From Workspace source block to use it if the data is time based. Or if the data is constant use the constant source block and put the name of your base workspace variable in there.
