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:

It means it is a 2x3 matrix of struct objects - i.e. 6 objects of a struct, arranged in 2 rows and 3 columns
