% script constructing a collateral reduced basis space for localized
% space operators.
%
% required variables that need to be set:
%   - 'model'
%   - 'model_data'
%   - 'plot_params'
%
% optional variables that can be set:
%   - 'CRBfname': filename of MAT-file where the computed 'detailed_data'
%                 structure is stored. If this variable is empty, it is
%                 set to '[model.name, infix, '_CRB_interpol.mat'], where
%                 'infix' is set to either 'model.model_type' if existent
%                 or the empty string.
%
% generated variables:
%   - 'detailed_data': structure containing the collateral reduced basis
%                      spaces and information on the empirical
%                      interpolation computations
