In the matlab coder, how to create a variable that is unbounded or resizable in the function that is going to generate C code from MATLAB code?

In the picture above, the size of the variable tfg is defined as 140 :? by the matlab coder automatically. How could I modify the size to :?:? , which means the size of it is unbounded?
