Solving boundary value problems with BVP4C. Tutorial + Examples.

| Watch this File

File Information
Description

This tutorial shows how to formulate, solve, and plot the solutions of boundary value problems (BVPs) for ordinary differential equations.

The tutorial introduces the function BVP4C (available in MATLAB 6.0 and later), briefly describes the numerical method used, and illustrates solving BVPs with several examples and exercises.

The M-files for all the examples and exercises in the tutorial are available in the directory BVP_examples.

The directory BVP_examples_65 contains the files for the examples and exercises, updated to take advantage of features available in MATLAB 6.5 (R13).
Correspondingly, BVP_examples_70 contains files modified for use with MATLAB 7.0 (R14).

More information about solving BVPs in MATLAB, can be found in the paper

  A BVP Solver based on Residual Control and the MATLAB PSE,
  ACM TOMS, Vol. 27 (2001), No. 3, pp. 299-316.

Could anyone help me solve this problem:
Equation : d2y/dx2 + y = f(x)
Restrains: y(a) = m; y(b) = n.

Thank you so much for your help.

Why in the example 8 they can have more boundary conditions than equations?. I want to do something similar; solve a system of two equations with 4 boundary conditions, but matlab only let me put 2 boundary conditions.

There is a bug in example 4, which cause it to not follow the boundary values,
the correct res. function should be:
res = [ ya(1)
yb(1)
(ya(2)-yb(2)) ];
which is not dependent on T, instead of
res = [ya(1) - yb(1)
ya(2) - yb(2)
T*(-1/3)*(ya(1) - 0.7 + 0.8*ya(2)) - 1];

I can't understand how can I chose the right guess... and for examples the two guesses in example 1. Can somebody help me?

I was wondering to solve:

y1'=A1*y2'+B1*y3+C1*y4
y2'=A2*y1'+B2*y3+C2*y4
y'3=0
y'4=0

but I could not use the tutorial,

bvp4c is really helpful in bvps. I have a question,
to solve a bvp like
d^y/dx^2 + y=0 where y and x are both vectors how can I modify the code?

with ode45 solving initial value problems I have no problem,but to use bvp4c I have some problem,most of time I receive the message,
??? Error using ==> bvp4c
Unable to solve the collocation equations --
a singular Jacobian encountered.I try to change initial guess but I'm reiceving the same message.bvp4c need to be improved in order to help user strigling to solve two-point boundary value problems.

Hello, I want to solve 24 diffrential equations in matlab using BVP4C but it says singular jacobian . could you please help me

Its a very good tool fou boundary value problem. One can learn a lot of from this m.code.

02 Apr 2007 Vince Aderangi

It is a very good resource. However, the m files of examples could have more comments. For example, in example 1 it does not explain what is used as initial guess.

Mr.Kierzenka,thanks a lot.The tutorial is very useful.

Helped me a whole lot!! - from zero knowledge of Matlab to calculation of the polyelectrolyte density distributions in colloid crystals (involving nonlinear coupled systems of BVP's) in 3 weeks! Without bvp4c and this tutorial, i'd be torturing Fortran, c++ and myself as we speak.
