Recently I've been implementing a Bellman-Ford-like algorithm, and there is a recurring need for accessing arbitrary indices on a DBM. As an example, for a `N`-sized square matrix `M`, a part of the a…

I am trying to implement some custom CUDA kernels to speed up integration of a system of ODEs using VexCL and odeint-v2. With some kernels this works very well, but with my largest system of equations…

Hi,
In many applications one has to calculate FFTs in batches. A simple example would be if there are many data sets that have to be processed or if only certain dimensions in a multi-dimensional arr…

I am experimenting with std::tie to speed up assignment of complex expressions to the components of a multivector.
It seems that it's not possible to use tagged terminals inside the tie. Can I check …
