Problem in Code Generation for LookUp blocks

My row and column index values are defined using variable parameters(eg: x=xRow, y=yCol, where xRow=[1 2 3],yCol=[4 5 6]). But my z Table data is direct constant values(eg: [1:3;4:6;7:9]). Datatype of x,y,z is uint8

In the code generated for this lookup using RTW, x and y are declared as calibratable parameter whereas my z is declared as constant in the C file.

So this will be a problem in the "run time", this would not allow to change any value on the tables online. Therefore, for calibration purposes it's an issue.

Please provide me some suggestion(other than declaring z table data as variable param) to correct this.
