Is there any working library for Linear Algebra?
I only found BLADE, which seems to be abandoned and quite unfinished, and
Helix which only provides 3x3 and 4x4 matrices used in games :(
For D1 try Gobo and Dflat. Gobo has a bunch of wrappers for Fortran
libraries. Dflat is a higher level matrix/sparse matrix interface.
Works with Tango using Tangobos.

Dflat gives you also sparse matrix formats, if all you are interested
in are sense matrixes than blip
http://dsource.org/projects/blip
(using the gobo wrappers) has NArray that gives you a nice interface to
N dimensional arrays, and (compiling with -version=blas
-version=lapack) also gives you access to most of lapack functions.
With it you can do things like these:
import blip.narray.NArray;
auto m=zeros!(float)([10,10]);
auto d=diag(m);
auto d[]=arange(0.0,1.0,0.1);
m[1,2]=0.4f;
auto v=dot(v,arange(0.1,1.1,0.1));
auto r=solve(m,v.asType!(float));
auto ev=eig(m);
