YtoZMatrix

YtoZMatrix($orb$) 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 tesseral 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.

Input

$orb$ : An integer number, or a list of integer numbers, or a string that can be interpreted as a non-relativistic atomic orbital, or a list or strings.
Options:
- “addSpin” : bool determining if spin-space is considered in the matrix (resulting in matrices double in size). (Default true)

Output

$R$ : Rotation Matrix from a basis of spherical to tesseral harmonics.
