Hello eveyone. I have a problem.

In one of my label in a figure, I should use subscipts, in this way:

legend(['Identified \alpha_', num2str(ind)],['Exact \alpha_', num2str(ind)]);

Because ind is a number, it may have more than two cipher. So, if it wasn't an index, I would write:

legend('Text_1_0'),

But, because in this case my number is num2str(ind), if ind is more than 10, how can override the problem that only the first cipher is a suscript?

Thank you in advance!

Enclose your subscript in curly brackets.

plot(1:10)
legend('Text_{10}')

one of the (more tedious) solutions
- if(f) i understand you correctly

ind=123;
fh=@(x) sprintf('_%c',strread(sprintf('%d',x),'%c'));
leg=['Identified \alpha',fh(ind)]
% leg = Identified \alpha_1_2_3

Thank you both for the solution. But I like more the first solution. I've solved in this way:

legend(['Identified \alpha_{', num2str(ind),'}']);
