How to pass variables to a SimMechanics model from a Function?

I am attempting to run a simple SimMechanics model from a function, with a loop that allows me to run the simulation repeatedly with slight changes in the variables.

Unfortunately when I try to do this using a function the variable that sets the end time for the simulation cannot be read my the SimMechanics model, and I get an Error such as this:

"Error evaluating expression 'config.Tend' for 'StopTime' specified in the Configuration Parameters dialog for block diagram 'DoF1_FDv0': Undefined variable "config" or class "config.Tend"."

I can work round this by using a script as my top level 'function' but this isn't ideal, and I would like to work out a way around this issue. I have tried using global variables for the variables that the model needs to use, but this has made no difference.

Any suggestions would be most welcome!

Apologies if I have missed out any crucial information or this is a simple problem, this if my first post.

What does the loop look like in the function? Can you paste a small sample of code?

Values defined within a MATLAB function are not accessible to the MATLAB workspace. You can use the command assign() to make the value accessible to your Simscape Multibody model.
