Hello Friends,

Does somebody have ideas on the errors or suggestions, please,
It looks like two errors, One is the ‘length(varargin)<1’ another one is the ‘output argument not assigned’.
The function is listed below,

“Error in channel_gain_wrappers.macroscopicPathlossMap/cell_assignment (line 120)
if length(varargin)<1

Error using channel_gain_wrappers.macroscopicPathlossMap/cell_assignment
Output argument “b_” (and maybe others) not assigned during call to
“channel_gain_wrappers.macroscopicPathlossMap/cell_assignment”.

Error in LTE_init_generate_users_and_add_schedulers (line 185)
[ site_id sector_num eNodeB_id] =
networkPathlossMap.cell_assignment(UEs(u_).pos);”

function [b_ s_ s_idx] = cell_assignment(obj,pos,varargin)
if length(varargin)<1
x_ = pos(1);
y_ = pos(2);
else
x_ = pos(1);
y_ = varargin{1};
end
if max([x_ y_] < [obj.roi_x(1),obj.roi_y(1)]) >= 1
eNodeB_id = NaN;
sector_num = NaN;
elseif max([x_ y_] > [obj.roi_x(2),obj.roi_y(2)]) >= 1
eNodeB_id = NaN;
sector_num = NaN;
else
% Some interpolation could be added here, but not so useful to have so much precision, actually…
pixel_coord = LTE_common_pos_to_pixel([x_ y_],obj.coordinate_origin,obj.data_res);
s_idx = obj.sector_assignment(pixel_coord(2),pixel_coord(1));
b_s_ = obj.sector_idx_mapping(s_idx,:);
b_ = b_s_(1);
s_ = b_s_(2);
end
end
