How do I create a legend and include loop variable values in the labels while plotting a Matrix ?

 u = 1:2:10;
z_x = 1:10;
temp = [1:10;11:20;21:30;31:40;41:50];
figure,
                hold on
                for l= 1:length(u)
                    str = ['S =  ',num2str(u(l))];
                    plot(temp,z_x,'DisplayName',str);
                    
                end
                legend show

The above code displays one value of S multiple times. Since i'm plotting a matrix and want to produce a legend for each uniques curve only one. What correction should I make so that the each S value is displayed only once in the legend.

It is producing what you asked for? if not elaboarate more say for example what you want in one iteration the legend to be?

Is it not your plot is messy? What exactly you want? Why you would want to plot a matrix?

Thanks for your response. This code produces k =1 multiple times then k=2 another multiple times and so on...in the legend. I want it to give k=1,k=2...,one time only, corresponding to each curve.

u = 1:2:10;
z_x = 1:10;
temp = [1:10;11:20;21:30;31:40;41:50];
figure,
                hold on
                for l= 1:length(u)
                    str = ['S =  ',num2str(u(l))];
                    plot(temp,z_x,'DisplayName',str);
                    
                end
                legend show

I agree the above code is very messy. Pehaps this code will explain my problem more clearly.

m = rand(10,8);
plot(m)
legend(compose('s = %d', 1 : size(m,2)))

This worked...thanks a lot.
