integrate two vectors of data

Hi all

I have two vectors of data. They are the same length. I want to multiply them and integrate over a distance. How can I do this in MATLAB?

I saw many people asking the same question and no answer. Does it mean it cannot be done in MATLAB?!

doc trapz.

let me explain my purpose in a better way. I have a matrix 'p' of 300*300 drawn over x and y. So I have 2D plot of p. I want to integrate this p over x and y and then plot the resultant 300*300 matrix.

Trapz gives only one value!

Never mind. You are right. I got my value now
