| Abstract: | Summary An attempt is made to construct a scheme of numerical integration for the wave operator that can detect which kind of non-homogeneous term has acted over the data and later use this knowledge to integrate the operator in time. Data is generated with a wave initially at rest, and a scheme is presented to detect these functions and study how these values can be extrapolated in time to be used. The use of known functions to generate data is required only to check the effectiveness of the numerical device. |
