ode45是数值分析中的一种计算方法，具体课参考数值分析的书，白话点说就是一种计算机可以使用的积分方法，咱们计算积分的方法计算机不能用，为了让计算机可以使用人们就开发了各种数值方法，这些方法统称数值分析

In this case, Matlab provides a set of values (41 values). For example, t is a set of values range between 0 and 2.75. How can I specify that I do not want random values of t in the ODE? Here, I want t to range between 0 and 2.75 but I want a step size of 0.25 Than...
Open in MATLAB Online odefun Notenough input arguments. Errorin odefun (line 13) dudz(1) = u(2); When you invoke odefun by itself instead of by calling one of the ode*() routines such as ode45(), then you need to manually pass in valid para...
The ODE solvers in MATLAB®solve these types of first-order ODEs: Explicit ODEs of the formy′=f(t,y). Linearly implicit ODEs of the formM(t,y)y′=f(t,y), whereM(t,y)is a nonsingular mass matrix. The mass matrix can be time- or state-dependent, or it can be a constant ...
