Integrate Set of data from excel

Hi there,

I have a set of Data in excel: Column A and Column B.

First i import the excel in matlab and then i create a plot from the 2 columns.

Now i want to find the integral of these data.. Is that possible and how?

[Star Strider]

Use the trapz or cumtrapz function to integrate a vector.

so i have to do trapz(A,B) ? The set of data on A,B columns represent a function..

[Star Strider]

The first argument to trapz is the independent variable (optional), and the second (required or only argument) is the dependent variable.

I have no idea what ‘A’ and ‘B’ are, so I cannot answer that.
