OptimalSamplingMultiSubsetsFromSameSetΒΆ

% get K subsets of gradients from one given gradient set, such that
% gradients in each subset are evenly distributed.
%
% USAGE:
%   [gradCell,grb_result,indexMatrix] = OptimalSamplingMultiSubsetsFromSameSet(gradAll, param, grbParam)
%
% INPUT
%   gradAll            :  Nx3 gradient matrix, where each row is a point in sphere.
%   param.numSamples   :  Kx1 or 1xK vector which gives number of samples in K subsets
%   param.w            :  weight for single shell term. 0<w<1. Default value is 0.5.
%   param.sos          :  1 (default), use sos constraint
%                         0, do not use sos
%   param.ModelFile    :  string. If set, write the model into a file
%
%   grbParam.start     :  a warm start if provided
%   grbParam.TimeLimit :  time limit to terminate the program
%   grbParam.MIPFocus  :  MIPFocus
%
% OUTPUT
%   gradCell           :  Kx1 cell, each element is a gradient matrix.
%   grb_result         :  output from GUROBI
