Solve is applied to each pdMat component of a,
which results in inverting the positive-definite matrices they
represent.
# S3 method for reStruct
solve(a, b, ...)an reStruct object similar to a, but with the
pdMat components representing the inverses of the
matrices represented by the components of a.
an object inheriting from class "reStruct",
representing a random effects structure and consisting of a list of
pdMat objects.
this argument is only included for consistency with the generic function and is not used in this method function.
some methods for this generic require additional arguments. None are used in this method.
