WebbWhat is the difference between ODE and PDE? An ordinary differential equation (ODE) is a mathematical equation involving a single independent variable and one or more derivatives, while a partial differential equation (PDE) involves multiple independent variables and partial derivatives. Webbfor a second-order equation, specify the initial x, y , and d y / d x, i.e. write [ x 0, y ( x 0), y ′ ( x 0)] for a second-order boundary solution, specify initial and final x and y boundary conditions, i.e. write [ x 0, y ( x 0), x 1, y ( x 1)].
