Matlab to vhdl conversion

I am basically trying to convert my MATLAB code into vhdl using HDL coder. I have two function files but hdl coder allows me to add only one function. Hence i used both the functions in one .m file itself. The issue right now is that the 2nd function shows a warning like: "This function may not be used". I tried using and end statement for both functions but it doesnt seem to work. Can anyone please help me out.

HDL Coder supports a single entry point called DUT from which VHDL/Verilog is generated.

Consider making one top level dut.m file with the following interface and use it for HDL code generation.

function [y1, y2] = dut(u1, u2)

y1 = call_to_module1(u1);
y2 = call_to_module2(u2);

end
