How to find the definite integral?

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.

Hi,

The following documentation would help you in finding the the definite intergral value you need.

Definite and indefinite integrals - MATLAB int (mathworks.com)

Trapezoidal numerical integration - MATLAB trapz (mathworks.com)
