how to extract the overwritten values inorder to plot the graph

Could anyone tell me how to extract the overwritten values to plot the graph.

[KSSV]

How and why the values are over written? We cannot help you unless code is shown.

[Prabha Kumaresan]

code:

for t= 1:length(N_UE)
list_of_N_rng={[1,2,3,4],[5,6,7,8,9]};
for seed_idx = 1 : length(list_of_N_rng)
N_rng=list_of_N_rng{seed_idx};
for s=1:length(N_rng)
....
...
...
output1(t,s)=overall_throughput1 % final result of throughput calculation
...
...
end
end
end
dummyX = 1:length(list_of_N_rng);
figure
plot(dummyX,output1,'rs');
hold on;grid on;

for the above code i can get the values for [5,6,7,8,9] displayed on the graph.But i couldnt get the values for [1,2,3,4].Could you please help me on this.

Check to see if output1(1) is nan or inf

[Walter Roberson]

This code does not agree with the output posted in the seemingly-the-same question https://www.mathworks.com/matlabcentral/answers/392992-could-anyone-help-me-how-to-plot-the-overwritten-values

[Prabha Kumaresan]

yes that data was different one. For the list_of_N_rng={[1,2,3,4],[5,6,7,8,9]}; the results are

Below results are for rng = 1
output1 =   1.9341e+10
Below results are for rng = 2
output1 =   1.0e+10 *    1.9341    1.6240
Below results are for rng = 3
output1 =   1.0e+10 *    1.9341    1.6240    1.9231
Below results are for rng = 4
output1 =   1.0e+10 *    1.9341    1.6240    1.9231    1.6755
Below results are for rng = 5
output1 =   1.0e+10 *    2.0917    1.6240    1.9231    1.6755
Below results are for rng = 6
output1 =   1.0e+10 *    2.0917    1.8071    1.9231    1.6755
Below results are for rng = 7
output1 =   1.0e+10 *    2.0917    1.8071    2.0985    1.6755
Below results are for rng = 8
output1 =   1.0e+10 *    2.0917    1.8071    2.0985    1.8008
Below results are for rng = 9
output1 =   1.0e+10 *    2.0917    1.8071    2.0985    1.8008    1.3841

[Walter Roberson]

You are three loops deep at the point you assign to output1(), but you only index output1 with the first and third loop variables. Everything for the second loop (seed_index) is going to be overwritten.

[Prabha Kumaresan]

ok.could you please help me how to index output 1 with respect to first,second and third loop variables.

[Prabha Kumaresan]

I have modified

 output1(t,s)=overall_throughput1

to

output1(t,seed_idx,s)=overall_throughput1

and I am getting the following output

Below results are for rng = 1

Now could you please help me to plot the values of [1,2,3,4] and [5,6,7,8,9] separately in one graph.

[Walter Roberson]

I am confused about what the differences are between the three different questions you have going that look to me to all be about the same topic.

[Prabha Kumaresan]

Sorry to confuse.What I actually need is I want to plot the values for [1,2,3,4] and [5,6,7,8,9] separately in one graph for the following code

for t= 1:length(N_UE ) 
list_of_N_rng={[1,2,3,4],[5,6,7,8,9 ]}; 
for seed_idx = 1 : length(list_of_N_rng ) 
N_rng=list_of_N_rng{seed_idx }; 
for s=1:length(N_rng ) 
.... 
... 
... 
output1(t,seed_idx,s)=overall_throughput1 % final result of throughput calculation 
... 
... 
end 
end 
end 
dummyX = 1:length(list_of_N_rng ); 
figure 
plot(dummyX,output1,'rs '); 
hold on;grid on;

If i run the code the result which I am getting are

Below results are for rng = 1

output1 =

But I am unable to get the graph for the above result.
Could you please help me to solve it.
