Backward compatibility for MATLAB in the examples

[lordmendonca]

I am a MATLAB R2017b user adhering to the toolchain requirements. I want to study the example(s) provided in order to naturally adapt to my requirements. However, the examples use the 'ss' function, which is not supported in MATLAB 2017. Therefore, I would recommend providing an example with backward compatibility.

I am try to run the .m file t00_basic_tutorial, but there are occurs the Error with Error using mex
mpc_solver_plain_C.c
D:\spcies_root\Spcies-0.3.10\generated_solvers\mpc_solver_plain_C.c(739): warning C4013:

I have no idear why it is hapen
Furthermore, when i run spcies.m, why there are so many "?" in the list of ansower.

This issue seems to be the one reported in #49. We are currently looking into it, and hope to have it solved in the near future. Could you please confirm if you are using Windows operating system and what version of Matlab?

Furthermore, when i run spcies.m, why there are so many "?" in the list of ansower.

I'm sorry, but I don't understand what you mean here. If you run spcies.m with no arguments, i.e.,
>> spcies
some basic help text should be printed in the command window. If you could provide more information such as the error message that you get when you run spcies we might be able to identify the problem.
