pass workspace matrix to simulink block parameter

Hi,

I simply want to pass a Matlab workspace variable that is a matrix into the A, B, C, or D parameters of the "Descriptor State-Space" block in Simulink. Can you tell me how to do this? I don't want to type in the matrix entries by hand in the dialogue box. I am hoping this can be done without any programming. I tried just entering the variable name on the input parameter field but got an error message.

Thanks!

Can you please share the error message?

Yes, Shubham. The message is:

Invalid setting in 'ABCD/Descriptor State-Space' for parameter 'A'.

Hi,

As per my understanding you can directly use a variable in MATLAB workspace in Simulink. I suggest making sure whether the variable exists in MATLAB workspace. Another approach would be, initializing the variable in Model Callbacks like ‘InitFcn’ or ‘StartFcn’, which you can find in File>Model Properties>Model Properties.

Hope this solves your issue.
