bresch 9c41c06325 square matrix: add function to uncorrelate part of the matrix 2023-09-19 09:37:50 -04:00
bresch b612467593 square matrix: add partial trace computation
This is useful when we need the sum of some variances in a large
covariance matrix

bresch d03f242c04 DCM: use simplified conversion from unit quaternion
This is exactly equivalent for a unit quaternion (and only unit
quaternions should be used to encode a rotation)

Matthias Grob b1435c6e34 matrix: use output stream function template
to enable proper automatic output in gtest unit tests
that compare two `Matrix`, `Vector` or two `Dual` objects.

Credits to @jwidauer for showing me this trick.

Eric Katzfey 34c852255e Changed M_PI to M_PI_F in the matrix library since M_PI is non-standard. (#20458)
* Changed M_PI to M_PI_F in the matrix library since M_PI is non-standard.

* Added a new M_PI_PRECISE constant definition to px4_platform_common/defines.h to be
used in places when M_PI is desired but shouldn't be used because it is not C standard.

* Added the px4_platform_common/defines.h include to the matrix library math.hpp header to pull
in some non-standard M_PI constants and updated the test files to use those constants.

* Fixed PI constants in matrix helper test to prevent test failure
