What are the most widely used C++ vector/matrix math/linear algebra libraries, and their cost and benefit tradeoffs?

http://stackoverflow.com/questions/1380371/what-are-the-most-widely-used-c-vector-matrix-math-linear-algebra-libraries-a

to any of these choices over another I ended up using Eigen3 which I am extremely happy with c math matrix linear algebra.. the realm of traditional graphics geometry applications. Eigen Benefits Clean API fairly easy to use. Includes a Geometry module.. not rendering focused. Probably not as performant as Eigen. LAPACK Benefits Very stable proven algorithms. Been around..

Best C++ Matrix Library for sparse unitary matrices

http://stackoverflow.com/questions/2222549/best-c-matrix-library-for-sparse-unitary-matrices

to use general purpose C matrix library I tend to use Eigen I used to use NewMat in the past . Advantages quite fast on.. Disadvantages IMO single processor Edit partly fixed in Eigen 3.0 slower for larger matrices and some advanced math than ATLAS.. or Intel MKL e.g. LU decomposition Edit also improved in Eigen 3.0 only experimental support for sparse matrices Edit improved..
