摘要

PROBLEM TO BE SOLVED: To increase the process speed of numerical calculation including a similar function by a computer by performing the numerical calculation from a specific expression by using the computer equipped with an input device, an output device, a storage device, and an arithmetic unit. ;SOLUTION: Numerical calculation wherein the convolution of an arbitrary value _1mh(t) of a variable (t) of a similar function Gh(t) and an arbitrary function _sg(t) is put over a variable 1 m is performed while the term of the left side of the expression is replaced with the term of the right side by using the computer equipped with the input device, output device, storage device, and arithmetic unit. Thus, the similar function _gh(t) is used in the expression, so a term _1mξ(t) of superposition can represent by using a delta function and the delta function δ77) is all 0 except (t)=0, so subsequent numerical calculation of superposition can be processed extremely easily.;COPYRIGHT: (C)1999,JPO
