WebSolve the ODE y = A B t y. Rewriting the equation as a first-order system yields y 1 = y 2 y 2 = A B t y 1. odefcn, a local function included at the end of this example, represents this system of equations as a function that accepts four input arguments: t, y, A, and B. Webis also sometimes called "homogeneous." In general, an th-order ODE has linearly independent solutions. Furthermore, any linear combination of linearly independent functions solutions is also a solution.. Simple theories exist for first-order (integrating factor) and second-order (Sturm-Liouville theory) ordinary differential equations, and arbitrary ODEs …
