Hi, When i was using this piece of code below few months ago, it was running ok. Now its throwing in errors, but displaying the graph somehow. But these red lines when i run the code bothers me. Can you please help me regarding this.

#######################CODE#########
W = [100 200 300 300 400 100 200 200 400 200 100 100];
DG = sparse([1 1 1 2 2 3 4 5 5 6 7 8 ],[2 3 4 5 6 4 6 7 9 8 8 9],W,9,9);
h = view(biograph(DG,[],'ShowWeights','on'));
######################################

The most simple way to solve this problem is to note the Line 32 to 35 of the hgCorrectFontSize.m.
just like
% if strcmp(h.showWeights,'on')
% edgeFontSize = max(h.edgeFontSize * scl,minAllowableFontSize);
% set(mycell2mat(get(mycell2mat(get(h.Edges,'hgline')),'UserData')),'FontSize',edgeFontSize)
% end
But this way maybe have an other negative effect.
The best way is to correct these codes.
My solution is to change the code of mycell2mat function begins from Line39 and save.
function m = mycell2mat(c)
if verLessThan('matlab','8.4.0')
% execute code for R2014a or earlier
if numel(c)==1
m = c;
else
m = cell2mat(c);
end
else
% execute code for R2014b or later
n=length(c);
m=gobjects(n,1);
for i=1:n
m(i)=c{i};
end
end

This seems to be a known issue. Currently there are no workarounds to resolve the errors.

I'm struggling the same story, 'ShowWeights' triggers the problem!
