ifs_similarity_dimension — MATH construct op

使い方

Moran’s equation sum(r_i**d) = 1 solved for d — from the maps alone.

The similarity dimension of a self-similar set, computed before anything is drawn. Valid when the pieces overlap only on a set of measure zero (the open set condition); affine maps that are not similarities (the fern) have no single ratio, so this raises rather than returning a number that looks right (measured: the fern’s four maps have singular-value ratios from 0.16 to 0.85, so no r_i exists).
