Solving Boundary Value Problems for OrdinaryDi erential Equations in Matlabwithbvp4cLawrence F. Shampine Jacek KierzenkayMark W. ReicheltzOctober 26, 20001 IntroductionOrdinary di erential equations (ODEs) describe phenomena that change contin-uously. They arise in models throughout mathematics, science, and itself, a system of ODEs has many solutions. Commonly a solution of inter-est is determined by specifying the values of all its components at a single pointx=a. This is an initial Value problem (IVP). However, in many applications asolution is determined in a more complicated way. A Boundary Value problem (BVP) speci es values or equations for solution components at more than onex. Unlike IVPs, a Boundary Value problem may not have a solution, or mayhave a nite number, or may have in nitely many. Because of this, programsfor Solving BVPs require users to provide a guess for the solution desired.
Eigenvalue problems, more speci cally Sturm-Liouville problems, are exem-pli ed by y00 + y =0 with y(0) = 0, y(ˇ) = 0. Such a problem obviously has the trivial solution y(x) 0, but for some values of , there are non-trivial solutions. Such are called eigenvalues and the corresponding solutions are called eigenfunctions. If
