GETFIELD  GETFIELD Get Field Contents


Usage
 
 Given a structure or structure array, returns the contents of the
 specified field.  The first version is for scalar structures, and
 has the following syntax
 
    y = getfield(x,'fieldname')
 
 and is equivalent to y = x.fieldname where x is a scalar (1 x 1)
 structure.  If x is not a scalar structure, then y is the 
 first value, i.e., it is equivalent to y = x(1).fieldname.  
 The second form allows you to specify a subindex into a
 structure array, and has the following syntax
 
     y = getfield(x, {m,n}, 'fieldname')
 
 and is equivalent to y = x(m,n).fieldname.  You can chain multiple
 references together using this syntax.
