How to integrate using Matlab 2012a?

Hello,

How can I integrate using MATLAB 2012a? I wish to integrate precipitation over land so that I get an accumulation of precipitation with time.

I have seen the function 'int' but this is just for newer versions of MATLAB.

I have a 3d matrix x*y*t

thanks, Michael

Hello Micheal,

First see if you can simply use sum instead of intergral. If not then chech the link below plz.

at the end of the page you can finde related similar functions that may also be helpful. Like if you don't have a function of your data and you need to do it numerically, for which you may check

doc trapz
doc cumsum

And so more.

Good Luck!
