How do I average the columns for the respective rows to draw a graph?

Hi!

So right now I have a data set of 76x2000, so thats 76 rows with 2000 data each. I want to average those 2000 data, and get a single value for each of the 76 rows.

After this, I want to graph those single values as the y-axis, and x-axis as 1-76 "units".

Thank you very much for your help!

This works:

M = randi(99, 76, 2000);                 % Create Matrix
RowMean = mean(M,2);
x = 1:size(M,1);

figure(1)
plot(x, RowMean)
grid

Hi! thanks for the reply, in this case, is M the data set? and do I just write that as a function? I already have A = 76x2000 data in my workspace. Thanks!

My pleasure!

In my code, ‘M’ is your data matrix. You just include the code I wrote in your script, wherever you want it, after assigning ‘A’.

If ‘A’ is your data matrix, my code becomes:

RowMean = mean(A,2);
x = 1:size(A,1);

figure(1)
plot(x, RowMean)
grid
