Designing a matrix library for D

[David Bregman via Digitalmars-d]

Have you looked at armadillo for inspiration? 
http://arma.sourceforge.net/

It's a C++ matrix/linear algebra library which has:
-expression templates for high level optimizations (could be done 
even better in D of course, moving more stuff to compile time)
-high performance via lapack/blas
-deliberately matlab-like syntax which is appealing to a large 
subset of people who would use such a library

I think this approach would also be good for D, at least if the 
idea is to target numeric computing people. I am skeptical about 
making the library too generic, since performance is typically a 
primary concern for matrix code. I didn't read the linked paper, 
but the performance quoted in the abstract "comparable (from 48% 
to 100%) to that of lower-level Java programs" sounds pretty 
underwhelming.
