Passing a block paramater value from App Designer to Simulink

5 views (last 30 days)
Hi, I'm using App Designer to build an app to control a Simulink model. I want to change a block parameter value in Simulink and run, so I have the following lines executed when I hit the "run" button
function RunSimButtonPushed(app, event)
I had defined a global parameter called Mode1 in my app
properties (Access = public)
SimOut % Output from Simulink model run
Mode1 % mode1 value, to be used by the Simulink model
When I run the app it gives me this error: "Undefined variable "app" or class "app.Mode1.Value""
Any ideas how to fix that? Thanks.

The quotes in the third argument of the set_param command seem quite unnecessary. If app.Mode1.Value holds a numerical value you need to typecast it to string data type using num2str function.
