Numerical algorithms and template meta programmiming

Here is an article about template-meta-programming and numerical algorithms. It illustrates how one can construct an numerical algorithm during compile-time. The example for this technique is the family of explicit Runge-Kutta solvers for ordinary differential equation.

Run-time performance of expression trees

A few days ago, I played around with proto, a C++ library the for construction and evaluation of expression trees. I wanted to write a small application allowing me to write classical vector operations in a neat way like b+2*c+d*e. With proto this is possible with only a few lines of code. Surprisingly, it turned out that the run-time performance for large expressions was about 10 to 20 percent better than a naive implementation. Continue reading
