Generate a row vector of length n+1

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

Shortest *and* exhaustive. Has there ever been a shorter answer in this forum? Perhaps "No." or "19"?
