einspline is a C library for the creation and evaluation of interpolating cubic basis splines (B-splines) in 1D, 2D, and 3D. It supports both uniform and nonuniform meshes, single and double precision, and real and complex data.

All pairs n-body simulation of electromagnetic forces on charged particles, adapted from Nvidia SDK 3.2 sample. Uses Lorentz force from EM fields via the Biot-Savart law for moving charged particles (uses relative velocity). Relativistic.
