In our previous article about construction of the discrete Laplacian with numpy we discussthe discrete Laplacian calculation for numerical solving of diffusion PDE. Here we generalize this technique for the two-dimensional space. We describe the complete algorithm of solving of reaction-diffusion equations with implementation of Crank-Nicolson scheme for diffusion part together with Runge-Kutta scheme for […]

In this article we considercalculationof discrete Laplacian for 1D arrays usingpython/numpy/scipy. We introducethe sparse matrix technique that is rather efficient for computation of certain types of diffusion PDE.
