Averaging specified number of points around the minimum value

Hi,

I'm trying to average a specified number of points around the minimum value of my data (ex. 5 points to the left and 5 points to the right) and cannot seem to find a solution. I'm just not sure how to create that range.

I'm assuming it would be something along the lines of mean(min( %my range)).

Thanks in advance for any help!

So you have an array "data", the minimum is at data(ix) for some index "ix" and you want to compute the average of [data(ix-5:ix-1),data(ix+1:ix+5)] ?

Yes, thank you! Why include the ix+/-1?

data(ix-5:ix-1) are the 5 points left to the minimum, data(ix+1:ix+5) are the five points right to the minimum.

So the code should be

[~,ix] = min(data);
max_left = min(5,ix-1);
max_right = min(5,numel(data)-ix);
avg = mean([data(ix-max_left:ix-1),data(ix+1:ix+max_right)])

I see, thank you very much for your help!
