I have done some linear algebra in D. If you are comfortable 
calling C functions, you can easily call into existing solutions, 
because it is trivial to call into C from D. I use Gretl 
http://gretl.sourceforge.net/ because it offers a convenient 
interface to commonly used BLAS and LAPACK functionality. GSL is 
another good choice https://www.gnu.org/software/gsl/. This has 
worked well for me because I am using D as a drop-in replacement 
for C.

If you do not know C or otherwise want a D solution, there is 
SciD https://github.com/kyllingstad/scid/wiki. I've never had a 
reason to use it so I do not know how well it works.
