What should I know about array memory in ctrlsys?

Arrays must use Fortran column-major order (order='F'). Additionally, routines often modify inputs in-place, so passing copies is recommended to preserve original data.

Does ctrlsys support discrete-time systems?

Yes, many routines use a 'DICO' parameter where 'C' stands for continuous and 'D' stands for discrete-time systems.

How do I find the right routine for my task?

The skill uses a 2-letter prefix naming convention (e.g., SB for synthesis, AB for analysis, IB for identification) to quickly identify specific routines like sb02md for LQR design.

What is the ctrlsys library used for?

It is a C11-based library with Python bindings used for advanced control systems engineering, including analysis, synthesis, identification, and filtering.
