Hi everyone, I have 2 problems.

1-I want to plot a figure for each value of y its mean i should have 10 figures, i tried many cases but i only got 1 figure.

2- i want to get max(y) for each iteration. then max y for all iteration and i want to know the max y belong to which step.

M = eye(2,2);

C = [ 2 3; 1 5];

t = 1:1:10

for i = 1:1:10

y = M * C

plot (t, y)

y1 = max(y)

y2 = max(y1(1,:)) % scalar end

y3 = max(y2) % this is the max among all values of y for all steps

% for y3 i want to know its belong to which row in y2 ?

Thanks for your help, your help always appreciated

Accepted Answer

1) Before your plot() call, insert

figure();

2)

In the loop,

y2(i) = max(y1(1,:));

After the loop,

[y3, y3row] = max(y2);

But you're not changing C *inside* the loop - it's the same every single iteration.

so, how can i change it ? Sorry Im new in matlab.

in the example i just right down one matrix for C but actually i got C from another loop so its more than one matrix. does this program always use one of C matrices or each time will change C?

The way you wrote the code, there is only one C so it will use only that one C.
