There is no declaration of vectors in Matlab, you can pre-allocate memory by creating your array with zeros or whatever you want.

You cannot just declare a vector of a certain size without giving the elements a certain value.

A = zeros(64,1);
B = ones(64,1);
C = NaN(64,1);

These are three ways to declare a vector mit 64 elements. The first (A) is a vector of zeros, the second (B) a vector of ones and the latter (C) one of NaN.
