Runge Kutta order 3

I have a function Funtion [t,u] = rk3(f,t0,tf,u0,n)

I am struggling defining the output argument t and u

The output argument t to be generated is a row vector of length n+1 containing the times t0; t1;...; tn and the output argument u to be generated is an array of size 2x(n+1) with the 1st column of u being u0 and with the (i + 1)th column of u being the approximation ui for i = 1;...; n.

i know that u(:,1)=u0 will set the first column of u to u0 and that u(:,i) refers to the i-th column f the matrix

would i be right in assuming that u(:,i+1) is the (i+1)th column?

any help will be appreciated. Thank you

Please, Patricia, avoid double posting a question. Althout neither Rick's nor mine answer took a lot of time. But inspecting both of them reveals, that they have the same contents. Therefore this is a waste of your time and of the time of all readers in this forum.
