Why is MATLAB compiling in alphanumeric order

I have a MATLAB file which is just compiles a some FORTRAN files via mex. I'm using the Intel 2015 FORTRAN compiler. For some reason the MATLAB chooses to compile the files in alphabumeric order which screws up the compilation. When it starts the it lists all the linking it has to do

Then it starts the compilation but compiles in the order _0, _1, _10, _11, e.g. alphanumeric. Why does it do that and how do I prevent it from it doing it?
