1D Multigrid Solver For Finite Element Method

Computational code using the Multigrid Method with the combination of the Finite Element Method to solve a mathematical problem is quite rare in the public domain. Usually, the mathematical problem can be solved using only one of those two methods. A sample of such code written in MATLAB programming...
