MATLAB Online에서 열기 I tried to solve these ODE equations but there is an error! This is my code: 테마복사 syms x1(w) x2(w) x3(w) T=773.15; R=1.314; K=(3.35e+24)*exp(-(70e+3)/(1.987*T)); Keq=exp(53.47-(27330/T)); ode1=diff(x1,w)==((-K*...
MATLAB Online에서 열기 I want to solve a system of 4 nonlinear ODEs with two variables x and y. I'm using the code below to try to achieve the solution. g = @(t, x, y) [ gamma2/2/pi*((x(1)-x(2)) / ((x(1)-x(2))^2 + (y(1)-y(2))^2)); ...
Ah, that actually wasn't what I was thinking (I don't know why, b/c in retrospect your question makes perfect sense). Anyway, that actually makes the answer fairly easy: yes. See Thanks
problem well enough to be solvable. As of now you have told us that you have 4 coupled ODEs...

Explicit Solution to ODEs While explicit solutions can be found in some areas of calculus, it’s rare to find an explicit solution for a system ofordinary differential equations(Shampine et al., 2003). The only possibility for many ODEs is to find an approximate numerical solution (Allaire et...
