David Dewey	17374ff5e8	AP_Math: fast_atan2 ... This is 126us per call vs 199us on the AVR. it is accurate to about 0.28 degrees Committed by rmackay9 but contribution is from David Dewey	2014-06-06 18:50:41 +09:00
Randy Mackay	d81b7b507d	Math: add Leonard's fast tan function	2013-05-30 18:24:32 +09:00
Andrew Tridgell	ba83950fc4	libraries: replace constrain() with constrain_float() ... this makes the type much more obvious. Thanks to Tobias for the suggestion.	2013-05-02 10:25:40 +10:00
Andrew Tridgell	83dc7dbc92	AP_Math: handle NaN in constrain(), returning average ... this makes it less likely a NaN will propogate	2013-04-15 14:28:51 +10:00
James Bielman	5631f865b2	Update floating point calculations to use floats instead of doubles. ... - Allows use of hardware floating point on the Cortex-M4. - Added "f" suffix to floating point literals. - Call floating point versions of stdlib math functions.	2013-01-16 13:52:01 +11:00
Andrew Tridgell	38062bbb6d	AP_Math: support some more rotation combinations	2013-01-13 17:32:48 +11:00
Andrew Tridgell	a072afa223	AP_Math: expand some macros into functions ... this saves some flash	2012-12-20 14:52:38 +11:00
uncrustify	533860dd73	uncrustify libraries/AP_Math/AP_Math.cpp	2012-08-21 19:03:34 -07:00
Andrew Tridgell	58a68c89d9	Math: added a function to combine standard rotations ... this will allow us to have an overall board rotation plus a per-sensor rotation	2012-03-19 17:29:02 +11:00
Andrew Tridgell	4422486d44	AP_Math: made rotation matrices more C++ ... thanks to Adam for the suggestion	2012-03-11 15:37:07 +11:00
Andrew Tridgell	9f0cb78f08	AP_Math: re-work quaternion functions to be more C++ like ... thanks to Adam for the suggestion!	2012-03-11 15:37:07 +11:00
Andrew Tridgell	4d65cda0ea	AP_Math: added quaternion->matrix and earth frame routines ... this will be used for 3d acceleration	2012-03-10 10:34:31 +11:00
Andrew Tridgell	8abbbe5713	AP_Math: better way of handling safe_sqrt() ... better to test the result, than predict it	2012-03-10 10:34:31 +11:00
Andrew Tridgell	c7d5f06b21	AP_Math: added quaternion helper functions and a test suite	2012-03-10 10:34:30 +11:00
Andrew Tridgell	16ed8bc8f6	AP_Math: added rotmat <-> euler functions ... these will make the dcm matrix manipulation easier to understand	2012-02-24 11:52:55 +11:00
Andrew Tridgell	17d16bc8c6	AP_Math: added safe_sqrt() function ... this function will never return NAN. It will return zero for negative numbers.	2012-02-24 11:52:55 +11:00
Andrew Tridgell	502fbf6e17	AP_Math: added a safe_asin() function ... this adds range checking to asin()	2012-02-24 11:52:55 +11:00
