How can I handle global variables in matlab coder?

Dear friends, I need to convert a m file to mex file using matlab coder. On this m file I had some global variables (I have a initial value and, solving any equations, I update this value) I need to use a file for save it or you know a better way? Tanks!!

The below has some fixed-point specific points in it, but I have often found the fixed-point documentation to have a lot of useful information about code generation; see for example the discussion about when the variable needs to be synchronized:
