Here is the code I have..
X = zeros(1,length(data));
Y = zeros(1,length(data));
for i = 1:101
temp = strsplit(data{i},',');
X(i) = str2double(temp{3}); Y(i) = str2double(temp{4});
end
for i = 102:length(data)
temp = strsplit(data{i},',');
X(i) = str2double(temp{2}); Y(i) = str2double(temp{3});
end
In this code the length(data) is 10, and What should I do if I want to find the absolute value of Y(i) from 0 to 1200?
like this.

1/X(end)*trapz(X,abs(Y))
Why do you repeat your question ? It was already answered in another thread.
