STRUCT STRUCT Structure Array Constructor

Usage

Creates an array of structures from a set of field, value pairs.
The syntax is

   y = struct(n_1,v_1,n_2,v_2,...)

where n_i are the names of the fields in the structure array, and
v_i are the values.  The values v_i must either all be
scalars, or be cell-arrays of all the same dimensions.  In the latter 
case, the
output structure array will have dimensions dictated by this common
size.  Scalar entries for the v_i are replicated to fill out
their dimensions. An error is raised if the inputs are not properly matched (i.e., are
not pairs of field names and values), or if the size of any two non-scalar
values cell-arrays are different.

Another use of the struct function is to convert a class into a 
structure.  This allows you to access the members of the class, directly 
but removes the class information from the object.
