Fast algorithms for spherical harmonic expansions, II
We provide an efficient algorithm for calculating, at appropriately chosen points on the two-dimensional surface of the unit sphere in R, the values of functions that are specified by their spherical harmonic expansions (a procedure known as the inverse spherical harmonic transform). We also provide an efficient algorithm for calculating the coefficients in the spherical harmonic expansions of ...
متن کاملFast Algorithms for Spherical Harmonic Expansions
An algorithm is introduced for the rapid evaluation at appropriately chosen nodes on the two-dimensional sphere S2 in R3 of functions specified by their spherical harmonic expansions (known as the inverse spherical harmonic transform), and for the evaluation of the coefficients in spherical harmonic expansions of functions specified by their values at appropriately chosen points on S2 (known as...
متن کاملSparse recovery for spherical harmonic expansions
We show that sparse spherical harmonic expansions can be recovered from a small number of randomly chosen samples on the sphere using `1-minimization. To this end, we establish the restricted isometry property of an associated preconditioned random measurement matrix.
متن کاملFast algorithms for spherical harmonic expansions, III
We accelerate the computation of spherical harmonic transforms, using what is known as the butterfly scheme. This provides a convenient alternative to the approach taken in the second paper from this series on “Fast algorithms for spherical harmonic expansions.” The requisite precomputations become manageable when organized as a “depth-first traversal” of the program’s control-flow graph, rathe...
متن کاملA fast and stable method for rotating spherical harmonic expansions
In this paper, we present a simple and efficient method for rotating a spherical harmonic expansion. This is a well-studied problem, arising in classical scattering theory, quantum mechanics and numerical analysis, usually addressed through the explicit construction of the Wigner rotation matrices. We show that rotation can be carried out easily and stably through ‘‘pseudospectral” projection, ...
