Another method to solve a system of ODEs for multiple initial conditions is to rewrite the ODE function so that all of the equations are solved simultaneously. The steps to do this are: Provide all of the initia
Solve ODE with Multiple Initial Conditions For simple ODE systems with one equation, you can specifyy0as a vector containing multiple initial conditions. This technique creates a system of independent equations through scalar expansion, one for each initial value, andode45solves the system to produce...

Basically, I want to know if theres a way to corral ode45 into solving a system of ODEs such as this one, since I couldn't find a built-in way to do it when searching, or if there's some mathematical trick to where I can transform the system to ...

Thanks, that is what I was looking for, the method I was using was very slow in comparison (a shooting method where I had to solve my system multiple time until I get the right initial conditions) 댓글을 달려면 로그인하십시오....
Next, solve the second-order differential equation d2ydt2=a2y with the initial conditions y(0)=b and y′(0)=1. Specify the second initial condition by assigning diff(y,t) to Dy and then using Dy(0) == 1. Get syms y(t) a b eqn = diff(y,t,2) == a^2*y; Dy = diff(...
It looks like you're maybe expecting h to be changed after you exit the function, which will not be the case since all input arguments are "pass by value", not "pass by reference". I hope you know what those basic computer science terms mean. Thus your code is ...
Simulate Constrained Robot with New Initial Conditions Now use the state of the constrained robot before termination of integration as initial condition for the second simulation. Modify the input vector to represent steering saturation, that is, set the steering rate to zero. Get saturatedPsiDot...
