Dear All,
I would like to integrate something which is not defined by a function (anoymous or otherwise. The 'function' is defined by a set of values iod a varable (y) at a number of points defined in another variable (x). I want to integate y with respect to x.
Is there some way of doing this? Graphically I could plot y against x and find the area under the graph. Is this the way I ahould do it using Matalb or is there something more sophisticated?
All help will be welcome.
John
