Simulink constant parameter read inside Matlab Function block

Hi. I defined some Simulink parameters to the Model Workspace of a Simulink model. When used in a Constant block, the code compiles with no error. When used in a Matlab Function block, I get the 'undefined variable' error.

How can I use global parameters in the Matlab Function block, without having to add an input port for each parameter?

Thanks

My answer to this previous question should work for you.

This worked great, thanks

Answer 2

If you have sevral parameters with the same size , you can use one constant block with value

 [param1 param2     ...    paramn]

Thanks, it's an useful tip
