I have a problem asking me to solve a second order diffrential equation of the form;
-u"(x)+x^2u(x)=f(x), 0<x<1 subject to u(0)=0 and u(1)=0
i have to create a function file which implements a function y=e^(-x^4) cos(20x)
and another function file with first line of the form;
function [ x,U ] = centraldiff(n,f) with inputs n is such that n+1 is the number of divions of [0,1] and the second input is a string which gives the name of a function describing the function.
i will be extremly thankful for any help, as i have noclue to this lab question.
thankyou

The function bvp4c should be able to get you started.
There are some nice examples in the documentation for bvp4c that should help you out. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/bvp4c.html
