Move average in the graph

Good Day all,

I have a 44568*2 and 437999*2 matrices, which I want to taking the average for each to calculate the residuals. Is there any sample command to do that.

your help is highly approciated

thank you

If you simply want the average of all the values without any consideration of matrix structure then simply

mean( A(:) )

works for any numeric variable A. If that isn't what you want you need to be more specific.

How to be more specific? the time series those I used are different in each size thus I want to average both of their values to calculate the residuals on one graph.

[Adam]

All you said was you had matrices of the given size. Without more information on how you want to average with respect to the structure of those matrices (e.g. average columns to give a 2-element vector or average rows to give a massive vector of results) the above works to simply average everything.

[Lilya]

both of them columns and rows

lina, what do the numbers represent??? For example is each row a point, and the first column are the x values and the second column are the y values? It's that kind of explicit explanation that you left out and Adam was (and still is) wondering about. I really think you need to read these guidelines.

OK, then we notice that the two arrays have different number of points, so you can't simply subtract them because they don't match up point for point. So, do you need to interpolate them so that you get a common set of x coordinates so that you can then subtract the y values to get differences?
