# Recomposition

Recomposition[decomp]

returns the reducible operator corresponding to tensor decomposition decomp represented on a space with smallest angular momentum sufficient to support all moments.

Recomposition[j,decomp]

returns the reducible operator on a space with angular momentum j corresponding to tensor decomposition decomp.

Recomposition[sys,mat]

returns the operator for atomic system sys corresponding to the matrix of tensor decompositions mat.

Recomposition[j,tens]

returns the operator that has the spherical tensor tens as the only nonzero component of its tensor decomposition.
