Introduction to Boundary Value ODE Problems<br />

The BVP solver is designed to handle systems <strong>of</strong> ordinary differential<br />

equations<br />

y′ = fxy ( , )<br />

where x is the independent variable, y is the dependent variable, and y′<br />

represents dy ⁄ dx .<br />

See “What Is an Ordinary Differential Equation?” on page 5-4 for general<br />

information about ODEs.<br />

Using Boundary Conditions to Specify the Solution <strong>of</strong> Interest<br />

In a boundary value problem, the solution <strong>of</strong> interest satisfies certain boundary<br />

conditions. These conditions specify a relationship between the values <strong>of</strong> the<br />

solution at more than one x . In its basic syntax, bvp4c is designed to solve<br />
