Just like a numeric array, a structure array can be scalar, vector, matrix, or ND. If you have been using structures already then most likely they were scalar structures.
Here is a scalar numeric array:
 X = 3
X has size 1x1.
Here is a vector numeric array:
X(1) = 2
X(2) = 3
X(3) = 5
X has size 1x3.
Here is a scalar structure array:
 S.field = 1
Here is a vector structure array:
 S(1).field = 2
 S(2).field = 3
 S(3).field = 5
The structure S has size 1x3. Read more here:
