# PrecomputedAssociatedEquations(R, L)ΒΆ

PrecomputedAssociatedEquations stores some generic precomputations which speed up the computations of the associated equations needed for factoring operators.

- firstUncouplingMatrix: (L, PositiveInteger) -> Union(Matrix R, failed)
`firstUncouplingMatrix(op, m)`

returns the matrix A such that`A w = (W', W'', ..., W^N)`

in the corresponding associated equations for right-factors of order`m`

of`op`

. Returns “failed” if the matrix A has not been precomputed for the particular combination`degree(L), m`

.
