Why is EIGEN restricted to square matrices?
why not support non-square matrices? does it really produce too much
complexity??? i have nonsquare matrices in my small vecmath class (
http://www.coreloop.com/dump/vecmath.h ). its not nearly as mature and
well tested as eigen, but anyway - i have nonsquare matrices and i would
miss them. i really would like to switch to eigen, though...
you could still keep efficiency and algorithms for square matrices via
partial template specialisation ala
template<class T> class Matrix<T,4,4>
// all these loop-unrolled fast functions go here
while having general functions via for loops in
template<class T, const int rows, const int cols> Matrix
in all other aspects i really like eigen. its exactly the complexity
level i like. no template meta magic like in tvmet, just straight but
fast vector matrix stuff.
by the way - is there any code that shows how to implement
pseudo-inverse calculation using eigen?
