For example, I have the following snippet:

A = [0 1 1; 1 0 0; 1 0 0];
names = {'V', texlabel('mu'), 'Q'};
params = graph(A, names);
h = plot(params);

And it yields a graph with a node labelled '{\mu}'. How can I get that to display as a µ character? I've tried setting the default interpreter of the figure to Latex and I've played with the formatting of the string. Thanks.

Hello,

Replacing 'mu' with '{\mu}' should do the trick. Nevertheless here is a popular link which eases your plot generation for latex

Hope it helps.

Thank you for the response! Unfortunately, that's not fixing it for me. Do you have any other suggestions? Are you able to take my code and produce Latex'd labels using the suggestion you provided me?

Thanks, Harry

bar(1:5)
set(gca,'XTickLabel',{'{\mu}','fgh','10','{\pi}','{\sigma}'})

like this? if you wanna store greek symbols in cell array you need to know the respective ascii code and then use char(ascii_code)

names = {'V', '\mu', 'Q'}; and changing 'tex' to 'latex' in the Figure properties editor solved the problem for me.

I have faced the same issue. This is a work around:

% you may need this before executing the code
set(groot,'DefaultTextInterpreter','latex')
set(groot, 'defaultLegendInterpreter','latex');
set(groot, 'defaultAxesTickLabelInterpreter','latex');
%plotting graph
A = [0 1 1; 1 0 0; 1 0 0];
names = {'V', '$\mu$', 'Q'}; % use $$ for the interpreter to read it as a equation
params = graph(A, names);
figure
h = plot(params);
h.NodeLabel = {}; %remove default labels
%creating labels as text
x_offset=0.05;
y_offset=-0.05;
text(h.XData+x_offset, h.YData+y_offset,names, ...
'VerticalAlignment','Bottom',...
'HorizontalAlignment', 'left')
