On an optimal scheme of calculating double integrals in solving direct gravimetric and magnetometric problems

© Legostaeva O.V.

In solving direct gravimetric and magnetometric problems it is proposed first to subdivide in the numerical calculation the integration range S into square (or similar) subranges Si, , and then to calculate m formed integrals by using the Cartesian product of the quadratures of Gauss-Legendre type. It is shown that the proposed scheme of the calculation of doubled integrals is most effective as to the convergence of the count compared to other schemes.
