I am given the following second-order ODE and I want to use ode45 and by not creating a function file. I am given the equation above, a timespan t, and initial y and dy values. I first set up my dydt into a matrix [y1' y2']" dydt = [y(2); eps...

Hi, I'm trying to solve the following acceleration equations: I currently have this code although I'm not sure if it's correct and when I ran it, MATLAB returned "Undefined function or variable 'xin'." function Yd= tennispin(t,Y) %constants alpha = 80*pi/180; r = 3.35; w =...
MATLAB Online에서 열기 You can create a function usable in the numeric ODE solvers by adding: 테마복사 [odes_vf, vfsubs] = odeToVectorField(odes); odes_fcn = matlabFunction(odes_vf, 'Vars',{w, Y}); [w,y] = ode15s(odes_fcn, [0 1], [2; 0; 4]); just afte...
Edited: Torsten on 10 Mar 2024 Open in MATLAB Online If you insert the line ThemeCopy size(dYdt(tspans(1),initial_conditions)) before the call to ode45, you will see that your function dYdt still returns a matrix of size 2x365 instead of a ...
You will also need to change your boundary condition function. Or actually, since you never use it except in the definition of the anonymous function bc and never use that anonymous function, just eliminate bc and your boundary_conditions function entire...
This paper explains and provides code to synthesize and control, in real-time, the audio signals produced by a dynamical system. The code uses only the Matlab programming language. It can be controlled with an external MIDI (Musical Instrument Data Inter
