Method for reducing the calculation time of a numerical calculation for a computer implemented superposition model

摘要

A method of reducing the computer calculation time of a superposition is disclosed. A computing device having an input unit, an output unit, a memory unit, and an operation unit, is used to calculate the model superposing the function with shifted value of the variable. The model operator is formed by superposing a delta function in the same manner as the superposition of the function. The convolution of a model operator and the function is determined to thereby reduce the calculation time of the model superposing the function with the shifted value of the variable.
