I am trying to get numerical data from the PDE Toolbox to prove Weyl's Law for differently shaped domains. I'd like to be able to export the eigenvalues of these domains back into the workspace so i can create the variable N(λ) from them. Any help would really be appreciated!

Hi Thomas,
I'm not entirely sure if this would work with your use case, but with most apps in MATLAB there is a corresponding way to do everything in them programatically. If you run the first example in 'solvepdeeig':

There is an example showing how to find the eigenvalues of a model using the PDE Toolbox programatically. Notice here how the eigenvalues are in the base workspace (stored in the variable called results.Eigenvalues). Is there something in your workflow that would prevent you from doing this programatically?
