Andrew Tridgell 6165c42535 AP_Math: added from_axis_angle() method on Matrix3f 
for arbitrary rotations in simulator

Lucas De Marchi fb28f426da AP_Math: remove check for AVR CPUs 
Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.

Andrew Tridgell c9ec8b3f67 AP_Math: added O3 optimisation to core math libraries 
this costs some flash space but speeds things up considerably

Andrew Tridgell 7aa7e03169 AP_Math: added euler312 functions (for gimbal) 2015-05-25 09:03:11 +10:00
Randy Mackay 9dede2f0ec Math: remove duplicate HALF_SQRT_2 definition 2015-05-05 14:23:14 +09:00
Andrew Tridgell 24b051565b AP_Math: added normalize() method to Matrix3f 2015-05-05 09:45:52 +10:00
Niels Joubert 879eb5936b AP_MATH: Adding WGS GPS conversions, CRC16 checks, and double-precision Vectors and Matrices 2014-04-05 13:42:23 +11:00
Andrew Tridgell 1e0f3f5398 AP_Math: make to_euler() const 2014-02-15 05:27:51 +11:00
Paul Riseborough f2c2811ef3 AP_AHRS & AP_Math: fixed bug in use of AHRS_TRIM parameters 2014-01-19 07:19:43 +11:00
Andrew Tridgell e2b0e07973 AP_Math: removed unused matrix rotation code 
we only need to rotate vectors
 2013-08-30 13:01:34 +10:00
Randy Mackay 540ca25b84 AP_Math: add rotateXY 2013-07-20 17:59:06 +09:00
Andrew Tridgell f4189e083b AP_Math: added mulXY() for matrix3 and vector3 
returns the XY components of the product

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.

Andrew Tridgell 38062bbb6d AP_Math: support some more rotation combinations 2013-01-13 17:32:48 +11:00
uncrustify d6e803fd3c uncrustify libraries/AP_Math/matrix3.cpp 2012-08-21 19:03:33 -07:00
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 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

Andrew Tridgell c16b353ea7 Math: added rotate() method to Matrix3f 
this is the core method used to update the DCM matrix with a gyro
vector. Moving it to AP_Math allows us to have a test for it
 2012-03-19 17:29:02 +11:00
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 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
