Hi This is toy code similar to what I want to achieve:

T = randi(10,10)
Q = randi(10,10)
hold on
for i = 1:10
for j = 1:10
plot(T(i,j),Q(i,j))
end
end
hold off

and my goal is to the corresponding elements of the two matrices in a plot. Yet it does not work - where is the problem?

The original code works fine. What errors are you referring to

It does indeed, but I had to restart Matlab. Formerly nothing happened. Another question though: Both my matrices are symmetric, and to reduce complexity I obviously do not want to plot the duplicate points (obviously plot(T(1,2),Q(1,2)) would be the same as plot(T(2,1),Q(2,1)) etc. Do you have a suggestion how I could achieve that?
