MATLAB based Finite element solver and Stochastic FEM solver for electromagnetics. Nedelec edge based finite element for 3D, specral stochastic FEM, stochastic collocation and Monte Carlo simulation.

created for the PhD thesis, "Stochastic Finite Element Modeling of Material and Geometric Uncertainties in Electromagnetics" The codes will be publisized after publication.

Usage Notes:

addpath 'emsfem/include' folder before executing the codes.

If 'buildKLMatrices' throws error due to incompatible c/c++ runtime libs, please recompile 'buildKLMatrices.c' using mex.
