Andrew Tridgell	a8fd31a5e1	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	d3dc5bd751	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	f2e6714598	AP_Math: added quaternion helper functions and a test suite	2012-03-10 10:34:30 +11:00
Andrew Tridgell	df6013616e	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	8190204287	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	1a32ececb4	AP_Math: added a safe_asin() function ... this adds range checking to asin()	2012-02-24 11:52:55 +11:00
