- fastlitz - Realistic litz wire characterization. Simulates litz wires in three-dimensions using the PEEC formulation. Computes the resistance of a wire, and the induced eddy loss when exposed to a magnetic field. Comes with a nice graphical user interface. [Associated paper] UPDATE 04/14: Removed dependencies on MATLAB Statistics Toolbox.
- pMag - Planar Magnetics Simulator. MATLAB software that implements several fast simulation techniques for planar magnetic devices. [User's Manual] [Associated paper].
- pFFT.m - MATLAB precorrected FFT. An implementation of precorrected FFT in MATLAB, with time-critical components written in C/C++ and precompiled for 64-bit Windows and Mac. Precorrected FFT accelerates surface / boundary integral equations, volume integral equations, molecular dynamics / n-body problems, to order near-linear complexity.
