Details

WARNING: This function does not work properly. Convert to a SS innovations representation with a minimum number of parameters by converting as much of H as possible to I matrix. Any remaining reductions are done by converting part of ?? to I. It seems there should remain n(m+2p) free parameters in F,G,H,K, and Om is determined implicitly by the residual.
