Nature of problem:A numerical integration rule is given for the calculation of three dimensional integrals on a spherical coordinate grid: integrals are considered as a weighted sum of integrand values. The program computes the points of the grid where the functions are to be determined and the associated weights. An example of integration is performed to normalize a numerical function. | ||

Solution method:Points and associated weights determination for numerical integration over a sphere or a spherical shell in separate spherical coordinates. | ||

Running time:1 second. |
