| Abstract: | In this paper we discuss the best approxilnation problem for matrices which is given in1]. We prove the existence of uniquencess of the best approximating solution and establish the expression and coinputng method of the best approximating solution. Soine examples are included to show that work load of Computing with our mefhod is less than that in 1]. |
