Fast method of moment (MoM) solvers implement advanced algorithms like the fast multipole method (FMM) or wavelet transform (WLT). Applying wavelet transform yields a sparsely populated matrix and enables fast iterative solvers. However, the effort of performing the transform itself may significantly add to the overall computational complexity. Traditional methods like multiplying with a change of basis matrix are very inefficient concerning time and memory demands. In this paper, new wavelet functions are considered enabling a fast wavelet transform that uses in-place operations and has low computational complexity.
