Hi Victor,

   For the last few years I have been working on a
set of C++ classes to do linear algebra. I was trying to
acheive most of the functionality of Lapack/Blas but
  in a very user friendly fashion. The classes center
arround a general purpose vector class along with a dense rectangular Matrix
class and then some more compilcated classes like a vector of vectors and
vector of matrices.
  All of them use operator overloading so you can write
    A = B + C * D where A,B,C, D are matrices and all of the operators
work for both real and complex matrices. Akll of the basic Linear algebra
functions are supported
ie solution of equations, decompositions, SVD eigenvectors etc. etc.
    The entire library is less than 5000 lines of code
and compiles into a static library of ~~ 3 megabytes
You don't have to compile it but you will need either a
Miccrosoft VC6 or Linux GCC compiler to use it.
   I have demo version available and if anyone in the group wants to play
with it and has a compatible compiler send me a line. Once you've used it
you will never go back to LAPACK
