Iterative legend for multple curves on the same plot

Hi

I have a 96xn matrix A where number of rows represent the quarters (of an hour) in a day.

I plot it in this way plot(x,A) where x=0.25:0.25:24.

How can I make an iterative legend? I would like to have a legend as curve 1, curve 2, ...... curve n and when n is very high it is very boring.

Thank you

you can do:

txt = cell(n,1);
for i = 1:n
   txt{i}= sprintf('curve %i',i);
end

legend(txt)

...and here is the trick to do it in one line:

legend(cellstr(int2str([17:28]')))

will just display the numbers in the array [17:28] in this case 17, 18, 19,... (The order of dimensions of [17:28] matters! Therefore in this case [17:28]' is used.
