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 results for each initial value. ...
% Initial Conditions tspan = [0 60] ; y0 = [1 1 1 0 0 0] ; % Solution [t, x] = ode45(@(t, x) odefcn(t, x, M, K), tspan, y0) ; % Results x_ = x(:, 4:end) ; xdot_ = x(:, 1:3) ; % Plot figure

ode45是啥 1) ode是常微分的英文缩写(Ordinary differential equation),定义为:凡含有参数,未知函数和未知函数导数 (或微分) 的方程,称为微分方程,有时简称为方程,未知函数是一元函数的微分方程称作常微分方程。 用通俗的话讲:i.e. 一个弹球,已知它的初始点与初始速度。它的加速度为重力加速度。接触地面后,速度...
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....
% start - a 3d vector or a cell contains multiple 3d vectors % stop - a 3d vector or a cell contains multiple 3d vectors % map - map generated by your load_map % path - n x 3 matrix path planned by your dijkstra algorithm
I too am very new to Matlab, and tried to run the code above in .m (JP Donlon on Nov. 7th). However, I keep getting an error stating "Not enough input arguments." I'm not sure what this means, because I have attempted to run other code by professors which works on other ...
You will also need initial conditions for the thetas and omegas. Then use ode45. 0 Comments Sign in to comment. Star Strideron 7 Feb 2023 0 Link Open in MATLAB Online This should get you started — symsc_1 c_2 k_1 k_2 k_n k_nl J_1 J_2 J_n theta_1(t) theta_2(t) the...
