04 Nov 2013 1D Wave Propagation: A finite difference approach This program describes a moving 1-D wave using the finite difference method Author: Praveen Ranganath Petrov, Lyuboslav

09 Oct 2013 Electric Field of a Parallel Plate capacitor using 2D Poisson Equation Electric potential and E-field of a cross section of a parallel plate capacitor is calculated. Author: Praveen Ranganath Abbott, Ben

The iterative solution can be sped up by about 30x by vectorizing the loops.

i = (2:Nx-1);
j = (2:Ny-1);
V(pp1,mpy-lp:mpy+lp) = 100;
V(pp2,mpy-lp:mpy+lp) = -100;
V(i,j)=0.25*(V(i+1,j)+V(i-1,j)+V(i,j+1)+V(i,j-1));

13 Jul 2013 Calculating Electric field of a dipole using Coulomb's law This code computes the Electric Field distribution due to a dipole in a 2-D plane. Author: Praveen Ranganath Rao, Sathyanarayan
