By the way, please stop adding answers just to respond to a question. Use comments. And, the immediate answer is exactly as Torsten said. If you replace both u and Tp with ones, then ODE45 never uses the values that are passd in for those variables. In terms of exceeding 1,...
[t, x, y] = ode45(g, [0 200], [y1_0 y2_0 x1_0 x2_0]); Where gamma1, gamma2, y1_0, y2_0, x1_0, and x2_0 are constants. Is there a way to use two variable like this? Or do I have to simplify the expression further by assigning y1 = x(1), y2 = x(2), ...
MATLAB Online에서 열기 Hello everyone. I tried to represent the following ODE system in Matlab but I don't know how to find if it has chaotic trajectory or not. Any ideas? ODEfcn = @(t,x,a) [0.25*(a*x(1)*(1-x(1))) - 0.0015*x(2) - 0.3*x(1); 0.25*x(1)*(1-...

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
The numerical analysis is done in MATLAB® using the ode45 solver for system of ordinary differential equations and using two methods. The FDM scheme uses 30 computational cells for the wall, 20 in insulation and 10 in the inner layer of the concrete or gypsum. An additional computational cel...
scalars y(2) and y(3) in the first position of the matrix dy. Whoever y(2) and y(3) are. no?? I think y(1) and y(2) should be something like variables x and z .. but what I think they really are is scalar numbers of a matrix y that I don't know what's in it.
