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

Andrew Tridgell 4422486d44 AP_Math: made rotation matrices more C++
thanks to Adam for the suggestion

Andrew Tridgell 9f0cb78f08 AP_Math: re-work quaternion functions to be more C++ like
thanks to Adam for the suggestion!

Andrew Tridgell 4d65cda0ea AP_Math: added quaternion->matrix and earth frame routines
this will be used for 3d acceleration

Andrew Tridgell 8abbbe5713 AP_Math: better way of handling safe_sqrt()
better to test the result, than predict it

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

Andrew Tridgell 17d16bc8c6 AP_Math: added safe_sqrt() function
this function will never return NAN. It will return zero for negative
numbers.
