Dear all, I have a loop that generates 30 matrices, each matrix represents some Y outputs to be plotted in a graph, how can i plot the 30 matrices on the same plot ? my code is
P_Single{K} = Values_S;
figure
plot(P_Single_9_jan{K})
but this code generates 30 graphs which i do not need. i want them all on the same graph please

Use the function matlab function "hold on", eg.,:
x = [1 2 3]
y = [4 6 7]
z = [7 8 9]
figure
plot(x,y)
hold on
plot(z)

It might be better to do a for loop. Eg.,
for i = 1:30
plot(x(i));
xlabel('X axis title');
ylabel('Y axis title');
hold on
end
title('Title')
You'll want to change the code depending on your data structure, but this might be a start
