Subsystem can not reference partitioned mask parameter

Question

0 个投票

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.
