Families of Self-Similar Symmetric Laplacians on the Interval and Sierpinski Gasket

The eigenvalues for both the interval and SG are in csv files.

For the threshold division scheme, the cutoff values are determined in the following way. Cutoff 1 is always 0, i.e. the standard division scheme. For the remaining 4, we take the two measure parameters, and choose 4 evenly spaced points between the values, excluding the smaller measure parameter and including the larger measure parameter. They are numbered in increasing order.
