Andrew Tridgell 97b7130bb9 libraries: update license header to GPLv3 
we switched to GPLv3 a long time ago, but neglected to update the
per-file license headers
 2013-08-30 13:01:39 +10:00
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

uncrustify 7e19ae5868 uncrustify libraries/AP_Math/matrix3.h 2012-08-21 19:03:34 -07:00
Andrew Tridgell 0ba57d05eb AP_Math: added matrix column extraction functions 2012-08-11 22:06:02 +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 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 31e566475b Math: added zero() and identity() methods to Matrix3f 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
 2012-03-11 15:37:07 +11:00
Andrew Tridgell 17170da96e AP_Math: added is_nan() methods to vector3f and matrix3f 2012-02-24 11:52:55 +11:00
Andrew Tridgell 62e92f406e AP_Math: make out vector and matrix elements used types with fixed sizes 
this prevents differences between CPU types

DrZiplok@gmail.com f10cbb011f ::transposed does not change the matrix; make it const.

DrZiplok@gmail.com 290635b354 Minor code size optimisation; use memset to zero *this rather than explicitly assigning zero to the vector elements. Still not quite optimal for matrix3 as it gets three memsets, but still cheaper in terms of code size.

rmackay9@yahoo.com 8708675b1f added constructor with 9 elements to matrix3.h 
corrected matrix * vector function.

DrZiplok@gmail.com 7721e622aa Rather than subclassing from the templated classes, just typedef directly to them. 
This should solve the issues related to assigning to the convenience types.

rmackay9@yahoo.com 15e6469ca9 added downcasting to MATRIX3_CTORS. this fixes some problems with setting the results from a formula to a variable (i..e m1 = m2*2).

rmackay9@yahoo.com b3e1b6c57d minor corrections to the operator *= and constructor so that matrix can be more easily created from vector objects

DrZiplok@gmail.com ac2e14c4ec Remove a bunch of probably wrong const cruft. Ditch the dubious array index operators from vector2.

DrZiplok@gmail.com 815e5f871a Remove the trivial operator= implementations, the default shallow copy is fine.

DrZiplok@gmail.com 646045ef44 Some minor fixes prompted while looking at the code for other reasons. 
Return non-const values from assignment.  Fix operator* for matrix3.

DrZiplok@gmail.com 097161cd8d Beginnings of a math library for ArduPilot(Mega) systems. 
The vector classes are light adaptations of work by Bill Perone
(billperone@yahoo.com), the Matrix3 class draws on them for
inspiration.

Bill's matrix classes are too heavyweight and not templated, so
they're less suitable for us here.

This code compiles, and some trivial tests seem to work, but
it should not be considered "golden" yet.
