findSynergyWeightsByGroup.m

% This function is part of the NMSM Pipeline, see file for full license.
%
% This function finds the synergy weights from the design variables and
% arranges them in an array where the first index indicates the synergy
% group a set of weights belongs to. This is used in the bilateral symmetry
% cost term.
