matlab - variable in plot title

Question

I want to do

for i = 1 : size(N, 2)
    figure(i);
    title(\'N = %d\', i);
%other stuff

but setting the title doesn\'t work. Why?

Answer 1

num2str should also works.

title(['N = ',num2str(i)]);

Answer 2

Because you forgot to add sprintf

for i = 1 : size(N, 2) 
figure(i); 
title(sprintf('N = %i', i)); %# %i for integer
%other stuff
end
