Hello,
Im trying to solve a set of ODE's with inital condition but for some reason the code fails and i cant seem to find the problem, would appreciate some fresh eye to see where im wrong.
the code:
%ODE45 Method
%Const
N0=25;G1=1;G2=1;a1=6;a2=3;k1=1;k2=4;ODE_Set=@(t,X) [G1.*(N0-a1.*X(1)-a2.*X(2)).*X(1)-k1.*X(1),... G2.*(N0-a1.*X(1)-a2.*X(2)).*X(2)-k2.*X(2)];%start position = (0,1)
ODE45_1_Ti=0;ODE45_1_Tf=10;ODE45_1_start=[0 1];[ODE45_1_T,ODE45_1_X]=ode45(@(t,X) ODE_Set,[ODE45_1_Ti ODE45_1_Tf],ODE45_1_start);
now the error it raises:
Error using odearguments (line 95)@(T,X)ODE_SET returns a vector of length 1, butthe length of initial conditions vector is 2.The vector returned by @(T,X)ODE_SET and theinitial conditions vector must have the samenumber of elements.
now i dont understand whats wrong with the initial conditions
Thanks in advance
