Matlab spherical harmonics

WebThe spherical harmonics arise from solving Laplace’s equation (1) ∇ 2 ψ = 0 in spherical coordinates. The equation is separable into a radial component R ( r) and an angular part Y ( θ, ϕ) such that the total solution is ψ ( r, θ, ϕ) ≡ R ( r) Y ( θ, ϕ) . As before, we’ll ignore the radial component and continue with only the ...
