Wrapper for functions related to periodic Schur decomposition

[RRiva]

Dear Slycot support,

SLICOT is probably the only library with an implementation of the periodic Schur decomposition, which is very useful in the analysis of Linear Time-Periodic systems. The main function is MB03WD, which needs MB03VD and probably also MB03XP and MB03YD. Could you please add a wrapper for these subroutines?

Thank you very much 😊

Best regards,
Riccardo Riva

Is #88 what you are looking for? MB03WX is used in the documentation example, but the unittest I built based on it succeeds without it.

MB03XP and it's auxiliary routines could be added, too. Can't promise if I find time in the next few days though.

Hi Ben, yes it is! It's nice to see how short the test becomes when it's written in python. Also declaring W as a complex array is a good idea.

I only needed MB03WD, so you can skip the other routines.

Thanks a lot 😊

Fixed in #88.
