Andy Piper 87a369727a AP_Math: specialize float and double functions to use fabsf() and simple comparison otherwise 2022-02-13 14:43:37 +11:00
Andrew Tridgell 999268cbba AP_Math: fixup matrix algorithms to be in cpp file 
this fixes an issue where optimize O2 was forced on any file that
included AP_Math.h. It also fixes the test suite for matrix_alg, and
fixes the type handling to be consistent

bugobliterator 3b3e2c01f8 AP_Math: templatize matrix_alg methods 2021-01-21 13:09:21 +11:00
Andrew Tridgell 720f9a1de0 AP_Math: cleanup maths functions 
use class template instantiation, and cleanup const in matrix code

bugobliterator 05fe49a51f AP_Math: disable INEXACT flag from Float exception 2020-05-17 16:12:43 +10:00
Andrew Tridgell 13a2367278 AP_Math: change optimisation from -O3 to -O2 2019-09-28 08:57:26 +10:00
Pierre Kancir 79a9e8dfad AP_Math: Matrix_alg fix implicite cast from bool to float 2016-12-05 12:39:31 -08:00
Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Gustavo Jose de Sousa b594b5a08b AP_Math: matrix_alg: disable FE_OVERFLOW in inverse4x4() for SITL 
There are occasional overflows on the determinant calculation in inverse4x4()
when using calibration SITL model.

Gustavo Jose de Sousa a7543d369f AP_Math: matrix_alg: protect inverseixi() against overflow 
Fail on inverse3x3() and inverse4x4() if there's float overflow during the
determinant calculation.

bugobliterator 1a4b4fa85e AP_Math: add inverse matrix test to check if inverse(mat)*mat = I 
where I is an identity matrix (a matrix with diagonal elements = 1)

bugobliterator fe62a049bd AP_Math: implement LU decomposition based matrix inverse 
Replaces previous matlab generated code, which was giving imprecise results

Tom Pittenger 103af93ec3 AP_Math: compiler warnings - float compare to constant (zero) 2015-12-07 16:04:59 +09:00
Andrew Tridgell c9ec8b3f67 AP_Math: added O3 optimisation to core math libraries 
this costs some flash space but speeds things up considerably

Gustavo Jose de Sousa 46774136a6 AP_Compass: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.
