Define global constant for HDL Coder

Hi, I use the HDL Coder Toolbox to generate Verilog code from my Matlab code.
I would like to use a global constant variable in my Matlab code in order to hardcode some values some specific global parameters. I know Verilog has a `define directive for global constant definition but the HDL Coder Toolbox does not allow the use of global statement in Matlab code.
Let's say my Matlab source code is :
global NROW_MATLAB_CODE ;
NROW_MATLAB_CODE = 31 ;
for kRow=1:NROW_MATLAB_CODE
% Process
end
Any idea of how to tell HDL Coder to insert a specific code line like `define NROW 5'd31 and make it use the string NROW wherever the variable NROW_MATLAB_CODE is used ?

Globals are not currently supported in HDL Coder. Use persistent variables instead.
