Integrate Data in MATLAB: Solving with FOR Loops

[TheFerruccio]

I've been reading up in the help files on MATLAB for this one, but it's a bit tricky.

I have been able to solve it on my own by using a FOR loop, but it's not completely accurate as it's just adding up rectangles at the average between two values.

Here's the problem:

Does there exist a MATLAB command that can integrate something based on just coordinates?

There are different numerical methods to achieve this.

Depends what you want to use. I don't know about the built in functions but it is easier to google for numerical integration MATLAB functions which can be used by your MATLAB file.
