Added tests for static gain, low-pass filter, differencer and summer for both classes. If the StateSpace DC gain computation fails due to singularity, return an array of NaNs of size (output,input), rather than scalar NaN. Added separate test for this for continuous- and discrete-time cases.

I compared the two alternatives using %timeit of Jupyter for matrices that would correspond to LTI systems with 10 state dimensions, 2 inputs, 2 outputs (so, the A matrix has shape (10, 10), B matrix has shape (10,2), etc.), and with 100 state dimensions, 20 inputs, 20 outputs, all using matrices from numpy.random.random((r,c)). The difference in timing performance does not appear significant. However, the case of `map` was slightly faster (approximately 500 to 900 ns less in duration), so I decided to use that one to resolve the merge conflict.

Allows StateSpace([],[],[],D), which failed previously. Static gains have sizes enforced as follows: A 0-by-0, B 0-by-ninputs, C noutputs-by-0.

On Python 2.7, the special case "all states useless" in _remove_useless_states resulted in A=[[0]] (and similarly for B and C). The special case is no longer needed, since empty A, B, C matrices can be handled. numpy.delete does the right thing w.r.t. matrix sizes (e.g., deleting all columns of a nxm matrix gives an nx0 matrix). Added test for this.

Following discussion on pull request #100 [1], I created a fork of Slycot at https://github.com/python-control/Slycot I created it without the GitHub semantics of forks, so you will notice that there is no small fork icon with links to <https://github.com/jgoppert/Slycot> or <https://github.com/avventi/Slycot>. I was thus motivated because 1. Slycot (and SLICOT) is currently an important part of python-control, and jointly maintaining it with `control` is easier if the fork is not temporary; and 2. avoiding the GitHub-fork-labeling reduces the chance of confusion in case python-control/Slycot diverges from its ancestors. If anyone prefers otherwise, now or later we can re-instantiate the site with GitHub fork semantics, all while preserving the Git repository URL. ~Scott [1] https://github.com/python-control/python-control/pull/100#issuecomment-240591506 |
