(4)y里面还含有一个未知常数C,如果我们再给定一个条件(x0,y(x0))=(0,1),就可以求出C=1,也就知道y的表达式是y=12x2+1 (5) ODE Solver 假设ODE是 dydx=f(x,y),y0=y(x0)(6)已知(x0,y0),能否计算出y(x_{0}+h)? 我们对等式两边积分,令x_{1}=x_{0}+h, ...

the solution is obtained iteratively. At each step the solver applies a particular algorithm to the results of previous steps. At the first such step, the initial condition provides the necessary information that allows the integration to proceed. The final result is that the ODE solver returns ...
Symplectic ODE solverBand-limited Collocation ImplicitRunge-Kutta method (BLC-IRK)We use generalized Gaussian quadratures for exponentials to develop a new ODE solver. Nodes and weights of these quadratures are computed for a given bandlimit c and user selected accuracy ?, so that they integrate...

Compared to ode45, the ode89 solver is able to obtain the solution faster and with fewer steps and function evaluations. Get function dy = twobodyode(t,y) % Two-body problem with one mass much larger than the other. r = sqrt(y(1)^2 + y(3)^2); dy = [y(2); -y(1)/r^3...
