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

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

Andrew Tridgell c30b0d85a3 Math: moved more template functions to the .cpp files
save a bit more code space for larger functions

Andrew Tridgell a6d66dc45b Math: added mul_transpose() operation
this is equivalent to multiplying by m.transposed(), but is more
efficient

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

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 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
