Webb@(T,U)ODEFUN(T,U,M,K1,C,NB) returns a vector of length 4002, but the length of initial conditions vector is 2. The vector returned by @(T,U)ODEFUN(T,U,M,K1,C,NB) and the initial conditions vector must have the same number of elements. I already had a look at the following questions but I do not understand where the problem could be.
