MATLAB: How to give initial condition as array in ode45

initial conditionmatrix-as initial conditionode45

I want to enter initial condition of 6×6 matrix in ode45.

How to do that? Any idea.

Please help

The ode45 initial conditions have to be a vector.

You have my interest, though. Why do you want them to be a matrix?

You are almost there!

Try this:

dydt = @(t,y) [y(2); eps*((y(1)^2) - 1)*y(2) - y(1)];
ic = [1 1]*eps;
tspan = [0 10];
[T,Y] = ode45(dydt, tspan, ic);
figure
plot(T,Y)
grid

That worked when I tried it. Change the initial conditions vector ‘ic’ to match your initial conditions, and ‘tspan’ to get the result you want.

To get the last values of the ‘t’ vector and ‘y’ matrix, use ‘end’ to define them:

t_final = t(end);
y_final = y(end,:);
