Hi, I need expand a spherical function(real function not a complex function) in terms of spherical harmonics. Expansion coefficients are complex numbers. If i need to observe physics quantities that are represented by the spherical harmonics coefficients which part should i look at- real part...

Now i got it. Thank you very much for your reply.

Could you please give little more explanation. Thanks

hello, I am trying to bin the unit sphere so that each bin has approximately equal area on the sphere. I hope binning the azimuthal angle (0...2*pi) to equal bin widths. Then i need to bin the polar angle(0...pi) so that at poles(angles close to 0 and pi) bin widths are large and close to...

Thank you for your valuable comments. Now I guess I have the algorithm to find two angles (teta and phi) of a given 3d vector. Here is the algorithm: // First find the vector AB. (vector AB= vector B - vector A). B=(x1,y1,z1) and A=(x2,y2,z2) // vector AB =(del_x, del_y, del_z); del_x =...

Hi, Can anybody help me to find the polar angle and the azimuthal angle of a given 3D vector? Say we know the ordinates of the two point A(x1,y1,z1) and B(x2,y2,z2). So the question is find angles (Theta and Phi) of the vector AB. Any suggestion would be really appreciated. Thanks. Susantha
