Hey,
your file s2 has only one column? Try to make length(s2). It should be the same as length(t).

What do you mean "not connected"?
For sure if you want to plot something in a given interval, the points of this interval have to have a correspondence to the values of the function. And Matlab works on that basis. Let's put in other terms: you cant plot vectors of different sizes, and we have to live with it!
