Newton Raphson m-file

I have to employ the newton raphson algorithm to find the positive real roots of f(x)=2xln(X)-1. I need to create a function m-file to do so. This is my first matlab assignment and I'm not really familiar with it. I don't really know how to go about the iteration and I'm not very confident with creating the function either. Any help would be greatly appreciated.

I would recommend to take a look at Cleve Moler's book Numerical Computing with MATLAB. Particularly in Chapter 4 which deals with finding the roots of functions with numerical methods.

Additionally, you can find a lot of submissions for Newton's Method in FEX.
