Hi there, I'm getting the following error when I try to type "1/(Ih+Ib)" into the parameter value of the Gain block in Simulink.

Both Ih and Ib are defined constants in the MATLAB workspace.

The error is: "Invalid setting in '.../Gain' for parameter 'Gain'."

Any advice on why this is not working. Seems like a simple thing that should not be a problem.

Thanks

why not define directly in the workspace :

gain =1/(Ih+Ib)

and use that "gain" in the simulink gain block parameter
