Integrating Expressions in MATLAB: Need Help!

[p3dro0]

hell, i have been trying to compute the integral of an expression in matlab, but when it comes to the integration part i can't get the right result. i tried the quad function, and one named romberg i found online. I have been told the ode23 function could work, but i can't figure out how to use it.

I've already created the function in MATLAB and tested it for some values, and they are correct, but when it comes to the integration part i can't get it right.

does anyone have some ideas on what can i do?

thanks

Until and unless you give us the expression, we cannot help you out. We need to know the nature of the error in order to provide a solution.

As a sidenote, quad is obsolete. Use integral instead:
