Subsystem can not reference partitioned mask parameter

I am trying to partition mask parameters for each subsystem block, however keep getting the following error while developing the C code:

Parameter 'a1' of block 'blankSystry/inputtry/Subsystem' cannot reference partitioned mask parameter 'i' of For Each subsystem 'blankSystry/inputtry' because parameter 'a1' will be reduced to a numerical value.

Caused by:

• The generated code will inline the numeric value of the expression 'a(i,1)' (used in parameter 'a1' of 'blankSystry/inputtry/Subsystem') because the expression is either referencing an element of a variable which is a mask parameter or has two or more dimensions, or is referencing an element of a one-dimensional variable using multiple indices. This expression resolves to tunable variables (i).

I have the same problem.

yeah, I finally converted those masked parameters as seperate inputs. There is no way around.

Hi Devyani,

I encountered a similar error with MATLAB R2022b. To resolve it, I changed the "Mask Parameter" property, “tunable” from “on” to “off”, which successfully generate code.

Currently I am using MATLAB R2023a and this issue does not occur in it, so you can upgrade your MATLAB version as well to resolve the same.

For your reference, I have attached a model.

The parameter needs to be a tunable. I should be able to change it.

[Devyani Varshney]

matlab version could be the reason though. I was using 2022b that time.
