Absolutely.

Sounds great!
During my time studying mathematics - in the last century, one Dr. of the mathematical department has developed a C++ library as glue to some fast C libs using the possibility of operator overloading, to make the formulation of matrix algorithms quite beautiful.

So would it be possible to get:

// Performs: c := alpha a x b + beta c
// glas is a pointer to a GlasContext
glas.gemm(alpha, a, b, beta, c);

transformed to something like:

Matrix A,B;
Real alpha,beta;
Vektor c;

c = alpha * A * B + beta * c;

Maybe not for performance but for readability purpose?

There was a recent thread about operator overloading but I didn't understood the problem.
(sorry, still a D newbie).

Regards mt.

Yes, this is possible. But, first we need a more low level interface. It will help to extend the Mir library and to write bindings for other languages (Julia, Python, R).

Thank you! Do you think the link should be announced in the news group? --Ilya

We usually post them in the threads where their content was announced. Doesn't appear to hurt anything.

And Facebook, too.
