where (compatibility equation)
we calculate matrices and , together with
diagonal matrices , , e , such that
the matrices of the symmetric model
satisfy the updating equation
and the no spill-over equation
stands for any set (generally unknown) of
eigenvalues - eigenvectors, which are not included in the updating.
Here, we provide an computer program to compute the set of
updating matrix parameters
. Once given the
input data corresponding to matrices
, and , the quantity
is computed, in order to validate the compatibility equation.
we provide a computer program to perform the simultaneous embedding.
