Filed: 1991-06-10
Abstract: PURPOSE:To solve an equation by performing only operations such as the substitution of a term, etc., and to shorten the calculating time by expressing a characteristic curve expressed by a nonlinear equation by a linear equation approximately by dividing the curve into sections. CONSTITUTION:A numerical analyzing device 10 provided with a parameter setting means 11 setting the data of each parameter for a nonlinear equation given by an input data 1 is provided with data segment means 12, linear approximation means 13 and a solving means 14. This data segment means 12 segments the set data into every preliminarily given area. The linear approximation means 13 decides a linear equation applied to the area by the data segmented into every area. The solving means 14 sets a matrix for the linear equation and outputs an output data to determine a solution. Namely, a characteristic curve expressed by a nonlinear equation is expressed by a linear equation approximately by dividing the curve into sections. Therefore, when the solution of the nonlinear equation is determined, the performance of a contrivance for convergence becomes unnecessary and the calculating time can be shortened.
