Hi everyone,
I have got the error in the code below, What should I do to fix it?
Code
% convert finite values to indices between 1 and map length
n = size(map, 1);
inds = (img(valid)-bounds(1))/(bounds(end)-bounds(1))*(n-1);
inds = floor(min(max(inds, 0), n-1))+1;
Error
Index exceeds the number of array elements (0).
Error in double2rgb (line 44)
ins = (img(valid)-bounds(1))/(bounds(end)-bounds(1))*(n-1);

Either img or bounds (or both) is empty.
Check img and bounds and figure out why one or both is not what you expect.

After the section above, for running code below I've got an error, what's the problem?
Code:
for ll = 1 : length(links) %% plotting links
line([EEG.chanlocs(links(ll,1)).X, EEG.chanlocs(links(ll,2)).X], [EEG.chanlocs(links(ll,1)).Y, EEG.chanlocs(links(ll,2)).Y], 'LineWidth', wij(ll), 'Color', rgb(ll,:) );
end
colormap(jet);
% colorbar
for nn = 1 : 4 %% plotting nodes
plot(EEG.chanlocs(nn).X, EEG.chanlocs(nn).Y, 'ro', 'MarkerSize', st(nn), 'MarkerFaceColor', 'y')
text(EEG.chanlocs(nn).X+0.5, EEG.chanlocs(nn).Y, EEG.chanlocs(nn).labels, 'FontSize', 11);
end
view([270 90]); %% rotating to vertical view
axis equal; axis off;
set(gcf, 'units','normalized','outerposition',[0 0 1 1]) %EXPANDING FIGURE ON SCREEN
Error:
Error using line
Value should be a finite number greater than 0
Error in NEW1 (line 452)
line([EEG.chanlocs(links(ll,1)).X, EEG.chanlocs(links(ll,2)).X], [EEG.chanlocs(links(ll,1)).Y, EEG.chanlocs(links(ll,2)).Y], 'LineWidth', wij(ll),
'Color', rgb(ll,:) );
Thanks in advance for your help.
Bests,
Neda

Ran in:
My guess is that wij(ll) is NaN or Inf or a non-positive number.
You can see below that those cases throw the error you got:
try
line([1 2],[1 2],'LineWidth',NaN)
catch e
delete(gca())
disp(e.message);
end
Value should be a finite number greater than 0
try
line([1 2],[1 2],'LineWidth',Inf)
catch e
delete(gca())
disp(e.message);
end
Value should be a finite number greater than 0
try
line([1 2],[1 2],'LineWidth',0)
catch e
delete(gca())
disp(e.message);
end
Value should be a finite number greater than 0
try
line([1 2],[1 2],'LineWidth',-1)
catch e
delete(gca())
disp(e.message);
end
Value should be a finite number greater than 0
