Here the last three numbers of the folder names correspond to the contraction ratios. Within the folders you will find the outer approximations and comparisons with the FEM results. The comparison of results are the excel files with a name starting with 'anna_baris_comp'. In excel files 'B N' means the normalized eigenvalues for outer approximation, and 'A N' denotes the normalized eigenvalues of FEM. Matlab variables named l1, l2,l3 are the eigenvalues of the zero, first and second level refinements respectively. Files starting with 'anna_baris_graph' are the graphs of eigenvalues for two different methods. The figure with a name containing 'mesh' is the picture of the outer approximation with a zero mesh. The matlab files including the letters p,e,t,g are geometry matrices. By using these in the matlab toolbox you can display the geometry and solve the eigenvalue problem. Except the one with number '63' all of them are at level 0.025, the level for '63' is 0.035.

In excel files 'B N' means the normalized eigenvalues for outer approximation, and 'A N' denotes the normalized eigenvalues of FEM. Matlab variables named l1, l2,l3 in matlabl are the eigenvalues of the zero, first and second level refinements respectively. Files starting with 'anna_baris_graph' are the graphs of eigenvalues for two different methods. The figure with a name containing 'mesh' is the picture of the outer approximation with a zero mesh. The matlab files including the letters p,e,t,g are geometry matrices. By using these in the matlab toolbox you can display the geometry and solve the eigenvalue problem. All of them are computed at level 0.025.
