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.
Most often the multiplication in convention descriptions and papers is
described in matrix multiplication style like this:
q · p := Q(q)p
Q(q) :=
[q0 −q1 −q2 −q3]
[q1 q0 −q3 q2]
[q2 q3 q0 −q1]
[q3 −q2 q1 q0]
I'm just rearanging the terms such that it's easily comparable with
these definitions additional to it being clearly described by
documenting we use the hamilton convention.
I want to switch the print() function back to use printf()
such that it's fully compatible with all (embedded) platforms.
To still test the print function I'm capturing stdout into a file
such that the print() function can stay unchanged and the result of
the printf()s can be evaluated.
This is important depending on the platform because norm()
calls matrix::squrt() which dispatches correctly to the implementation
for the used type. Otherwise float squrt()s can get calculated as
double.
* Fix compilation error
* Add implementation of pseudo-inverse
The implementation is based on this publication:
Courrieu, P. (2008). Fast Computation of Moore-Penrose Inverse Matrices, 8(2), 25–29. http://arxiv.org/abs/0804.4809
It is a fully templated implementation to guaranty type correctness.
* Add tests for pseudoinverse
* Apply suggestions from code review

* Add pseudoinverse test with effectiveness matrix
* Fix coverage
* Fix rebase issue
