Preon::Math

Preon::Math is a simple C++ math library that is used for all the basic math operations in PreonLab. It includes vector, matrix, euler angles and quaternion classes and basic linear algebra operations. It also includes SIMD variants for the most common operations.

Preon::Math is tested to compile with Visual Studio 2015 and GCC 7.

Changes

0.03 - 11.02.2020

• Added SymmetricMatrix33.
• Added .clang-format file and formatted all files with it.

0.02 - 02.20.2020

• Renamed vec::zeroVector() to vec::zero()
• Improved double-precision support (new cast methods in Preon::Math::cast, new templated operators).

Roadmap

• Port remaining unit tests from QTest to catch2.
• Doxygen documentation.
• CI builds.
• Extend unit tests to cover all classes and methods.
• Rename vec::zeroVector() to vec::zero() to match the matrix::zero() method.
• Add a all.h (or similar name) that includes all math classes/defines. Similar, all_fwd.h would be nice.
• Combine math_misc.h and math_utils.h.
• Compare MatrixUtil::fromQuaternion to RotationUtils::matrixFromQuaternions and decide on one variant. Delete the other.
• Remove ErrorHandling.h dependencies and exception throwing.
