Differential Equations I ~ To solve the separable equation y0 = M(x)N(y), we rewrite it in the form f(y)y0 = g(x). Integrating both sides gives Z f(y)y0 dx = Z g(x)dx, Z f(y)dy = Z f(y) dy dx dx. Example 2.1. Solve 2xy +6x+ x2 −4 y0 = 0. ∗ ∗We use the notation dy/dx = G(x,y) and dy )dx interchangeably. 5. 6CHAPTER 2. FIRST ORDER ORDINARY DIFFERENTIAL EQUATIONS Solution. Rearranging, we have x2 −4 y0 = −2xy .

deSolve: Solvers for Initial Value Problems of ~ Functions that solve initial value problems of a system of first-order ordinary differential equations ('ODE'), of partial differential equations ('PDE'), of differential algebraic equations ('DAE'), and of delay differential equations. The functions provide an interface to the FORTRAN functions 'lsoda', 'lsodar', 'lsode', 'lsodes' of the 'ODEPACK' collection, to the FORTRAN functions 'dvode .

ODEPACK - Ordinary Differential Equation Solvers ~ ODEPACK is a collection of Fortran solvers for the initial value problem for ordinary differential equation systems. It consists of nine solvers, namely a basic solver called LSODE and eight variants of it -- LSODES, LSODA, LSODAR, LSODPK, LSODKR, LSODI, LSOIBT, and LSODIS. The collection is suitable for both stiff and nonstiff systems. It includes solvers for systems given in explicit form .

Solve nonstiff differential equations — low order method ~ For this moderately stiff problem, ode23 executes slightly faster than ode45 and also has fewer failed steps. The step sizes taken by ode45 and ode23 for this problem are limited by the stability requirements of the equation rather than by accuracy. Since steps taken by ode23 are cheaper than with ode45, the ode23 solver executes quicker even though it takes more steps.

Solve nonstiff differential equations — medium order ~ ode15s and ode23t can solve problems with a mass matrix that is singular, known as differential-algebraic equations (DAEs). Specify the mass matrix using the Mass option of odeset . ode45 is a versatile ODE solver and is the first solver you should try for most problems.

CRAN Task View: Differential Equations ~ One also distinguishes ordinary differential equations from partial differential equations, differential algebraic equations and delay differential equations. All these types of DEs can be solved in R. DE problems can be classified to be either stiff or nonstiff; the former type of problems are much more difficult to solve. The dynamic models SIG is a suitable mailing list for discussing the .

An introduction to ordinary differential equations - Math ~ What are ordinary differential equations (ODEs)? An ordinary differential equation (ODE) is an equation that involves some ordinary derivatives (as opposed to partial derivatives) of a function.Often, our goal is to solve an ODE, i.e., determine what function or functions satisfy the equation.. If you know what the derivative of a function is, how can you find the function itself?

Collocation method - Wikipedia ~ Ordinary differential equations. Suppose that the ordinary differential equation ′ = (, ()), =, is to be solved over the interval [, +].Choose from 0 ≤ c 1 < c 2 < … < c n ≤ 1.. The corresponding (polynomial) collocation method approximates the solution y by the polynomial p of degree n which satisfies the initial condition () =, and the differential equation ′ = (, ())

Stiff equation - Wikipedia ~ In mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable, unless the step size is taken to be extremely small.It has proven difficult to formulate a precise definition of stiffness, but the main idea is that the equation includes some terms that can lead to rapid variation in the solution.

Bifurcation de Hopf — Wikipédia ~ Le cycle orbital (oscillant) est stable si la quantité spécifique appelée premier exposant de Lyapunov est négative (c'est-à-dire que toute petite déviation appliqué à un point du cycle limite décroit exponentiellement au premier ordre), et la bifurcation de Hopf est dite super-critique. Dans le cas contraire (premier exposant de Lyapunov nul ou positif), le cycle limite est instable .
