Andrew Tridgell 0bdce404a5 AP_Math: add include of math.h 
this is needed for location.cpp
 2012-07-04 13:59:23 +10:00
Andrew Tridgell dd200cba31 Math: added location functions to math library 
these do common calculations on struct Location

Andrew Tridgell fe865bc1dc Math: added comment 2012-06-27 16:01:49 +10:00
Andrew Tridgell c30b0d85a3 Math: moved more template functions to the .cpp files 
save a bit more code space for larger functions
 2012-06-27 16:01:49 +10:00
Andrew Tridgell 22ff8cb197 examples: fixed build of some examples with new AP_Declination code 2012-03-30 14:25:27 +11:00
Andrew Tridgell a6d66dc45b Math: added mul_transpose() operation 
this is equivalent to multiplying by m.transposed(), but is more
efficient
 2012-03-23 16:48:52 +11:00
Andrew Tridgell fe55a76335 Math: moved matrix multiple operations to .cpp file 
this means we only link this in once, rather than for every use of
matrix multiply, which saves us some flash space

We need to be careful not to put large pieces of code in template
headers, as if the operation is used a lot, it costs us a lot of code
space

rotation
 2012-03-19 17:29:02 +11:00
Andrew Tridgell 0ec9857689 Math: any euler angle with pitch > 90 is invalid 
both DCM and quaternion always return pitch in the range -90 to 90
 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 55aa43a70d Math: added a test suite for the new rotation methods 2012-03-11 15:37:07 +11:00
Andrew Tridgell 289c64c0b9 Math: added vector3.rotate() and matrix3.rotation() methods 
these operate on a "enum Rotation" which defines a set of standard
rotations. These are much faster than our previous method, plus use
less memory
 2012-03-11 15:37:07 +11:00

 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

 2012-02-24 11:52:55 +11:00
Andrew Tridgell 17d16bc8c6 AP_Math: added safe_sqrt() function

numbers.
 2012-02-24 11:52:55 +11:00
Andrew Tridgell 502fbf6e17 AP_Math: added a safe_asin() function

Andrew Tridgell 6efa2e53cb AP_Math: re-work polygon algorithm for perfect precision 
using sign checking and 64 bit integer math only when needed results
in an algorithm that is just as fast as the floating point version,
but has perfect results for any representable lat/lng
 2011-12-19 18:52:56 +11:00
Andrew Tridgell a3a0e5646f polygon: improve the speed and precision of the polygon algorithm

 2011-12-18 12:59:50 +11:00
Andrew Tridgell 42522baf9f geofence: store fence points as int32_t

Andrew Tridgell 9b6bab8904 AP_Math: better polygon algorithm 
this one seems to do better with single precision floating point
 2011-12-16 20:11:51 +11:00
Andrew Tridgell 62e92f406e AP_Math: make out vector and matrix elements used types with fixed sizes

 2011-12-15 14:42:34 +11:00
Andrew Tridgell 117a98f9a2 AP_Math: added a Polygon_outside() function 
this tests if a point is outside of a polygon. This will be used as
part of our geo-fencing support, and also for a new 'fenced mode'
 2011-12-15 14:34:58 +11:00
