Tyler Veness	8e2a7fd306	Include thirdparty libraries with angle brackets (#5578)	2023-08-28 15:13:34 -07:00
Tyler Veness	e322ab8e46	[wpimath] Fix docs for DARE ABQRN stabilizability check (NFC) (#5579)	2023-08-28 15:10:42 -07:00
Tyler Veness	03764dfe93	[wpimath] Add static matrix support to DARE solver (#5536) ... Using static matrices where possible results in a 2x performance improvement.	2023-08-14 09:15:58 -07:00
Tyler Veness	394cfeadbd	[wpimath] Use SDA algorithm instead of SSCA for DARE solver (#5526) ... Both seem to work, but the SDA algorithm is specifically recommended for solving DAREs as opposed to P-DAREs. The QR decomposition was replaced with a partial pivoting LU decomposition at the recommendation of section 2.4 of the paper. More tests and a separate JNI function for each DARE solver variant were added.	2023-08-12 19:45:45 -07:00
Tyler Veness	52bd5b972d	[wpimath] Rewrite DARE solver (#5328) ... I timed the DARE unit tests, and the new solver is 0 to 100% faster in all cases (that is, it's at least as fast as Drake's and up to 2x faster in some cases). The new solver is also much simpler, takes less time to compile, and drops the libwpimath.so size from 325 MB to 301 MB. I think most of the compilation time is coming from the eigenvalue decompositions used to enforce argument preconditions.	2023-05-14 22:23:00 -07:00
