Take the general model of collocation AmnmX+BrnrY=L+Δ (1) The current solution is found under the bi fitting rule (2), it has some shortcoming . This paper puts forward a two steps solution: 1. Term Y is incorporated into Δ , then find the best estimate under the singular fitting rule. 2. Term being incorporated into L, is found also under a singular fitting rule.
