Differential equations are very common in science and engineering, as well as in many other fields of quantitative study, because what can be directly observed and measured for systems undergoing changes are their rates of change. Note that the solution of matrix equations is an intimate part of numerical solutions to differential equations. An ordinary differential equation (ODE) is an equation containing an unknown function of one real or complex variable x, its derivatives, and some given functions of x.The unknown function is generally represented by a variable (often denoted y), which, therefore, depends on x.Thus x is often called the independent variable of the equation.
