Analyzes the effect of sparse sampling on a sphere

Analysis of sparse sampling for assessment of angular average of farfield power patterns from antenna arrays modelled as point sources. The angular average of the Equivalent Isotropic Radiated Power (EIRP) pattern is the Total Radiated Power (TRP) value. Here, the analysis is performed in the far-field of the sources. See https://arxiv.org/abs/1803.10993 for further details.
The angular average values are calculated on a spherical grid or on two or three orthogonal planar cuts (xy, xz and yz). A set of random antenna patterns are calculated. Each sample has a randomly selected: number of source points, rotation, and correlation level.
The inputs are: Size as diameter over lambda (wave length), number of sample points per 180 degrees, range of element weight correlation values, a flag to turn on/off random rotations, choice of numerical integration method.
The outputs are: angular averages on the three grid types, the sparsity factor (angular step divided by reference step where convergence is ensured), and array sizes used.
Four examples on code usage is provided in the function help.
