Abstract
A physical quantity analyzing method obtains estimated physical quantities O.sub.j at a predetermined point j based upon proportion constants .alpha..sub.ij and provisionally determines physical quantities u.sub.i. The method obtains a sum of squares of differences between the estimated physical quantities O.sub.j and known physical quantities S.sub.j at a predetermined point j given in a region as an error function E. The method corrects the provisionally determined physical quantities to an axis value of the error function E which is a parabola, so that an analysis of physical quantities within a system which is a linear system is improved in speed and accuracy. The number of species of physical quantities, which can be subjected to the present physical quantity analyzing method, is large.
