Returns the spherical harmonic expansion coefficients of the following quadratic form:
[x y z]*A*[x y z]'/norm([x y z],2)^2 = sum(r_LM*Y_LM)
Syntax
[r0,r1,r2]=qform2sph(A)
Parameters
A - a symmetric 3x3 matrix
Outputs
[r0,r1,r2] - coefficients for zero, first,
and second rank spherical
harmonics in the order of
decreasing m index of Ylm
