Daniel Agar 3679f7fd51 add double precision alias declarations and remove typedefs 2021-02-11 12:40:54 -05:00
Julian Kent 4837316f9b Fix small inconsistencies and compiler warnings 2021-01-22 17:30:00 +01:00
Julian Kent d540ca5de2 Coerce default epsilon values to Type 2021-01-13 10:17:09 +01:00
Julian Kent 054f8b12f4 Use a single inverse implementation for a single matrix size 2021-01-05 09:02:09 +01:00
Matthias Grob 7a3009f7a3 Remove asserts for unsigned integer >= 0 
GCC 10 gives a warning
"comparison of unsigned expression in ‘>= 0’ is always true"
for these asserts since checking if an unsigned integer cannot
be negative and hence the statement gets droped.

Matthias Grob 65679fbcbb Features and fixes 
* added the trace function for a SquareMatrix

* added Vector3.hat() and it's counterpart Dcm.vee()
for skewsymskew symmetric matrix operations in relation to the cross product
see https://en.wikipedia.org/wiki/Hat_operator

* Matrix::write_string produced runtime errors when I used it in PX4 posix simulation, i simplified it

* a Matrix3f is a SquareMatrix

* added tests for SquareMatrix.trace, Vector3.hat and Dcm.vee

* added a test for quaternion initialisation from array

* preventing buffer overflows in Matrix.write_string method
