Abstract
A computer readable medium is configured to determine the integral of the product of a plurality of functions. The computer readable medium includes logic configured to project each function of the plurality of functions into the wavelet domain, logic configured to encode basis coefficients of each function in a wavelet tree, each function being encoded in at least one wavelet tree such that the plurality of functions are represented in the wavelet domain by a plurality of wavelet trees, and logic configured to traverse direct paths through the plurality of wavelet trees to determine the integral of the product of the functions represented by the wavelet trees, along which direct paths an integral coefficient may be nonzero.
