Hey everybody,
ts me again with an maybe simple question for you. I have a for loop and calculate some data, which I plot at the end of each loop. Is it possible to define, that the legend will have an calculated data in it? Such as loop one z=1, loop two z=2.5 and so on.
Thanks in advance for some help

for eg:
z = 1;
%loop1
data1 = [1:10];% data obtained in loop1
z = 2.5;
%loop2
data2 = [1:2.5:25];% data obtained in loop2
plot(data1);
hold
plot(data2,'r');
legend('z = 1','z = 2.5');
xlabel('xaxis');
ylabel('yaxis');
grid on

str = {strcat('z = ' , num2str(z))} % at the end of first loop, z being loop output
str = [str , strcat('z = ' , num2str(z))] % after 2nd loop
% plot your data
legend(str{:})
