    Numerical integration!!!

    Hi all,

    I have a question which might sound silly to some of you (so I apologise in advance).

    I have a complicated function which I have evaluated numerically using Matlab.

    What information can I take out of this numerical integration? How can I use the outcome of a numerical integration to plot graphs etc?

    I know why we use numerical integration. I am trying to understand how can I use the result to draw conclusions about my function.

    Thanks

    Regards

    Alex

    In order to do a graph of an integral what you would be doing is something like this: Plot the series of points \left ( x, \int_0^x f(y) dy \right ) for several (that is to say a large number) of x values.
