plot only some points of a vector

Hi everyone,

I have a row vector of length N, I want to plot only few points of the vector, eg I plot the first point of the vector and then I jump 3 points of the vector and I plot the 5th and so on, keeping a regular step of 3 for instance. Please could someone help me to do that on Matlab?
