When x1(t)=sin(t) - no problem.
When x1(t) is my function - an error!

This is because the solution functions are defined using interpolation. The interpolation functions have the X and Y vectors and the value of x as arguments. You try to provide a vector for x. Vectorize can handle only matrix arguments of the same size and successively calls the function with the j-th element of each vector.

So vectorize would require your x vector to be of the same size as the data vectors. Even in this case this probably will fail because the data would be reduced to a single X_i and Y_i.

Therefore, you have to use a loop.

As I open your returned document,
