That is not necessarily impossible -- for example if interest = [0 1 2] then 1+interest would be 1 2 3 and interest ( [1 2 3]) would be valid. It is, however, rather suspect.speed (T) = -0.073.* (t.^2) + 6.1802.*t + 40.423; end. end. plot (0:0.1:25, speed) The first design pattern can be used even when the values are irregularly spaced or when it is difficult to calculate an index given a value.

After that, t(i) is one individual numeric value, and x_t(t(i)) would be a request to index x_t() at the location given by the numeric value in y(t) -- an indexing that could only work for the one location where y(t) is 1 exactly.
