Module assembly 

BEM matrix assembly

This module provides three methods for assembling BEM systems:

• tbem - Traditional BEM with O(N²) dense matrix
• slfmm - Single-Level Fast Multipole Method
• mlfmm - Multi-Level Fast Multipole Method

For small problems (N < 1000), TBEM is usually fastest. For larger problems, FMM methods provide O(N log N) or O(N) scaling.
