SPHERE_LEBEDEV_RULE_DISPLAY is a MATLAB program which reads the name of a data file defining a Lebedev quadrature rule for the sphere, reads the file, creates an "XYZ" file containing the coordinates of the quadrature poins, and then and displays a unit sphere and the points in the MATLAB graphics window.
The Lebedev quadrature rule file contains a table of values of theta, phi, and weights. The angles are measured in degrees. So it is helpful to have this program read the data, convert angles to radians, compute the XYZ coordinates (and save the values in a file) and then display the point set.
