In such cases, a numerical approach gives us a good approximate solution. The General Initial Value Problem One Step Methods of the Numerical Solution of Differential Equations Probably the most conceptually simple method of numerically integrating differential equations is Picard's method. Consider the first order differential equation y'(x) =g(x,y). (5.1.3) Let us directly integrate this over the small but finite range h so that ∫ =∫0+h x x0 y y0 the differential equation with s replacing x gives dy ds = 3s2. Integrating this with respect to s from 2 to x : Z x 2 dy ds ds = Z x 2 3s2 ds ֒→ y(x) − y(2) = s3 x 2 = x3 − 23. Solving for y(x) (and computing 23) then gives us y(x) = x3 − 8 + y(2) .

Differential Equations • A differential equation is an equation for an unknown function of one or several variables that relates the values of the function itself and of its derivatives of various orders. • Ordinary Differential Equation: Function has 1 independent variable. • Partial Differential Equation: At least 2 independent variables.
Using the state-space representation, a differential equation of order n > 1 is transformed into a system of L = n×N first-order equations, thus the numerical method developed recently by Katsikadelis for first-order parabolic differential Numerical integration software requires that the differential equations be written in state form. In state form, the differential equations are of order one, there is a single derivative on the left side of the equations, and there are no derivatives on the right side. A system described by a higher-order ordinary differential equation has to The essence of a numerical method is to convert the differential equation into a difference equation that can be programmed on a calculator or digital computer. Numerical algorithms differ partly as a result of the specific procedure used to obtain the difference equations. Selection of the step size is one of the most important concepts in numerical integration of differential equation systems.
Solving for y(x) (and computing 23) then gives us y(x) = x3 − 8 + y(2) . This is a general solution to our differential equation. To find the particular solution that also

Numerical integration, ordinary differential equations, delay differential equations, boundary value problems, partial differential equations The differential equation solvers in MATLAB ® cover a range of uses in engineering and science. We have presented a numerical integration method to solve a class of singularly perturbed delay differential equations with small shift. First, we have replaced the second-order singularly perturbed delay differential equation by an asymptotically equivalent first-order delay differential equation.
