Hi,
You can use simply a Newton method, it's easy for implementation and  
enough good in the most of case. if you have the optimization toolbox  
already installed then you can just use the function fsolve ( please read  
the documentation in matlab help) if not you can use an algorithm which is  
available online colled mmfsolve  
(http://www.nd.edu/~wschnei1/Courses/CBE_445/Fall06/Lectures/Lecture2/mmfsolve.m).
