WebApr 14, 2024 · If you can get Matlab to plot the spherical harmonics (as rho = function of (phi,theta)) in spherical coordinates and output the result as an array/table (preferably to a file), there's probably a way to get pgfplots to read them in as a color map for a sphere. That's likely your best bet if you want to be able to manipulate them using tikz. WebPython/numba package for evaluating and transforming Wigner's 𝔇 matrices, Wigner's 3-j symbols, and spin-weighted (and scalar) spherical harmonics.
