# Symbolic Processing with MATLAB. Differential Equations. A first-order ordinary differential equation (ODE) can be written in the form dy dt = f (t, y) where t is the independent variable and y is a function of t. A solution to such an equation is a function y = g (t) such that dgf dt = f (t, g), and the solution will contain one arbitrary constant.

The Second Edition integrates the science of solving differential equations with approach: Modeling, Mathematics, Methods, MATLAB(R), and Multiphysics,

ode (t) = diff (y (t), t) == t*y (t) Solve the equation using dsolve. ySol (t) = dsolve (ode) MATLAB offers several numerical algorithms to solve a wide variety of differential equations: Initial value problems Boundary value problems Delay differential equations Partial differential equations You can solve the differential equation by using MATLAB® numerical solver, such as ode45. For more information, see Solve a Second-Order Differential Equation Numerically . syms y(x) eqn = diff(y) == (x-exp(-x))/(y(x)+exp(y(x))); S = dsolve(eqn) Solve differential equations in matrix form by using dsolve. Consider this system of differential equations.

In this computer lab, we shall solutions is also a solution. ▻ If an ODE is not linear, most of the case it cannot be solved exactly: we will use MATLAB 9 Solve the following set of differential equations: Solving Simultaneous Differential Equations Example yx dt dx 43 += yx dt dy 34 +−= Syntax for solving The basic command used to solve differential equations is dsolve. This command finds symbolic solutions of ordinary differential equations and systems of Chapter 1: Classification of differential equations.
