Mean of 72720 rows in one column such that I can take mean of 720 rows separately.

Hello!

I have data of 72720 rows in one coloumn. I want to take the mean of each 720 rows and then plot a graph.

Thank you

Try this:

data = (1:72720)';                                  % Create Column Vector To Test Code
rdata = reshape(data, [], 720);                     % Reshape To Matrix
rdata_mean = mean(rdata);                           % Calculate Column Means

figure
plot(1:numel(rdata_mean), rdata_mean)
grid

Experiment to get the result you want.

Thankyou for your answer and if I have to find the maximum value of new re-shape formed such that I have to find out the maximum value in each coloumn. I have tried max (mean720) but it is giving me error. Can you please guide me related to it.

[Star Strider]

To find the maximum in each column in my code, add this line:

rdata_max = max(rdata);

data is your 72720 rows in one coloumn

mean720=mean(reshape(data,720,[]));
figure;
plot(mean720)

[Anas Rao]

The code is working but I don't know why in my MATLAB 'max or mean' function is not working. It is giving the following error. Can you please help me related to it. Thank you

[Walter Roberson]

Your A2 is a cell array, not a numeric array.

[Anas Rao]

@ Walter Roberson ! Sir, then how I would deal with the cell array? Can you please guide me?

[Star Strider]

We would have to see the rest of your code to be certain, however the cell2mat funciton would be worth trying on your cell array before doing any calculations on it.

[Anas Rao]

Thankyou Sir. It is now working. Actually I have made a mistake in the begining with exporting the data on the MATLAB. The command is making it into cell form rather then number. Thank you for your help

[Star Strider]

As always, my pleasure.
