1. Define the system of differential equations that describe the dynamics of your system. For example, let's consider a simple harmonic oscillator described by the equations: dx/dt = y. dy/dt = -kx. 2. Create a grid of initial conditions for the state variables x and y. This will be...

Open in MATLAB Online Assume that I want to solve the system of equations below for u and v. A and B are known numbers (say, 1 and 2 respectively) and a(t) is a fixed vector that I want to pass to the solution and get the result. How can I do it? The code works fine ...
Hello everyone, I got the solution below from the help, I tried an example with a 3x3 system and it runs ok. However, when I try to apply it to my real system, I can not find an answer. Do you have any idea why? Example: 테마복사 syms x(t) y(t) A = [1 2; ...

Hey all, I'm trying to use matlab to give me the fixed points for a system of differential equations written in all variables. Here's my specific problem I'm trying to do: dI/dt = s + p*I*T/(a+T) - c1*I*T - d1*I ...
Matlab's "dsolve" function can handle systems of ordinary differential equations (ODEs) and partial differential equations (PDEs) with ease. For instance, consider a system of two first-order ODEs: ``` syms x y t eqn1 = diff(x,t) == x + 2*y; eqn2 = diff(y,t) == x - y; ...
I have a question for system of ordinary differential equations, because Matlab gives some strange solution as output. There is the code: Jo1=1; Jo2=2; Jo3=3; Mo1=1; Mo2=1; Mo3=1; f=@(t,x)[x(4).*sin(x(3))./sin(x(2))+x(5).*cos(x(3))./sin(x(2)); ...
