Histogram with overlapping bins --> summing second argument

Hi,

I've got the following code:

load data.txt;

X = data(:,1);
Y = data(:,2);
m = [-60:1:12000];
k = [m; m+200];         % m+x: x is the width of the bin

NrEvents = NaN(1,size(k,2)); 

for i=1:length(NrEvents)

    NrEvents(i) = sum (X<=k(2,i) & X>=k(1,i) );

end

Like this I can calculate the number of data points for overlapping bins. Now I'd like to add another argument, summing the corresponding numbers written in column 2 of the data file for the same bins. I assume it works with 'cumsum' but I'm unable to find a way to kind of link 'cumsum' with the 'sum' function. Probably not a big thing...

Thanks for any help Stefanie

Starting from what you have, and I am not sure that is advisable:

SumY(i) = sum (Y(X<=k(2,i) & X>=k(1,i)));

Great, already worked. The cumsum might have messed it up...

Thanks
