微分求积法(differential quadrature) 有限差分系数(finite difference coefficients) 插值微分法(differentiation by interpolation) 2.1.8 微分方程 微分方程(differential equation)是一种描述导数与其函数关系的数学方程式。如果函数是一个物理 量,那么导数就是这个物理量的变化率,微分方程就是这个物理量和其变化率的关系。

There are symplectic solvers for second order ODEs, the stiff solvers allow for solving DAEs in mass matrix form, there’s a constant-lag nonstiff delay differential equation solver (RETARD), there is a fantastic generalization of radau to stiff state-dependent delay differential equations...
method(string or odsolver):It is used to specify which integration method to use like RK45, Radau, RK23, DOP853, BDF, and LSODA. t_eval(array_data):It is used to specify the times at which to store the calculated solution.
