Simulink Code Generation: blocks with masks and tunability

Is is possible to generate tunable code from a masked block with parameters in the mask?

For example:

In the Matlab Workspace:

>> K100 = Simulink.Parameter(1.0);

A masked Simulink Block has a parameter with "Name" 'P'. In the mask I introduce K100, so P has a value of K100.

Now, P is accessible under that mask, where it takes the same value of K100.

Is there a way to generate code from that block and ensure that the C code retains tunability (if K100 changes)?

Thanks

Create Tunable Calibration Parameter in the Generated Code

Thanks, that worked, but I am having issues with arrays, for example:

>> K100 = Simulink.Parameter([1 2]);

'P' takes that from the mask input, and under the mask I use a Gain block with, for example P(1).

Tunabilty is lost in this case. Is there any workaround?

Thanks again.

I remember this is one of the limitations for tunability, although I can't pinpoint the exact reference in this link.

Maybe just turn on the " Detect loss of tunability" to see if it detects it and point you to the reference.
