Hi, I was busy with exams so I couldn't do much the last 2 weeks. Today I finished with the Neumann Series implementation and will start on a Laplace/Fourier transform module next week. This will be used to implement one of the few techniques that give closed form solutions for integral equations. It can also be used to solve certain boundary value problems. Please feel free to give any suggestions or design tips.
