The MATLAB ODE solvers do not accept symbolic expressions as an input. Therefore, before you can use a MATLAB ODE solver to solve the system, you must convert that system to a MATLAB function. Generate a MATLAB function from this system of first-order differential equations using matlabFunction with V as an input.

2.3 Systems of ODE Solving a system of ODE in MATLAB is quite similar to solving a single equation, though since a system of equations cannot be defined as an inline function we must define it as an M-file. Example 2.2. Solve the system of Lorenz equations,2 dx dt =− σx+σy dy dt =ρx − y −xz dz dt =− βz +xy, (2.1)

Feb 01, 2008 · Exercises using more efficient MATLAB ODE solvers or finite-element techniques are omitted because they do not serve this immediate purpose. In part II of this article, we hope to share MATLAB codes which can be used in conjunction with teaching topics pertaining to angular momentum and non-commuting observables.
