Modal functions and natural frequencies for an elliptic membrane are computed using Mathieu functions. Symmetric and anti-symmetric modes with Dirichlet or Neumann boundary conditions are allowed. Graphics animation or contour plots of the mode shapes are provided. The command listfunctions describes the workspace contents and the command open('MembranePaper.pdf') shows a document describing the mathematical formulation. Function runelip is the main driver program. The code runs under MATLAB 8.3 (R2014a)
