-alligned paragraph text+YtoKMatrix($orb$) takes the angular momentum $l$ or the name of a non-relativistic atomic orbital and returns the corresponding matrix to rotate from a basis of spherical harmonics to cubic harmonics. It is also possible to give a list of $l$ numbers or orbital names, in which case the output is a block diagonal matrix with the rotation matrices as entries.
