I am using the following matlab embedded function in a Simulink Model. When I run the simulation I am getting an error "num2str is not supported for Code Generation "

Is there any way so that we can use all available matlab function is simulink??

function yy=fcn(u)
%%%ASCII Code Generation of Numbers of Characters
in_number=u ;
%%%Conveting the incoming number to String
in_string=num2str(in_number);
%%%creation of empty row to fill with ascii numbers
max_index=length(in_string);
out_ascii=zeros(1,max_index);
i=1;
for j=drange(in_string)
      out_ascii(i)=abs(j); %%%ascii equivalent number of the string
      i=i+1;
end
yy=out_ascii;

Below code supports code generation.

function str = num2strc(num) %#codegen
   str = [];
   while num > 0
      data = mod(num,10);
      str = [char(48+data), str]; %#ok
      num = (num-data)/10;
   end
end
