eq

PURPOSE ^

EQ overloads the == operator for cdata objects.

SYNOPSIS ^

function result = eq(c1,c2, varargin)

DESCRIPTION ^

 EQ overloads the == operator for cdata objects.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

 DESCRIPTION: EQ overloads the == operator for cdata objects.

              All fields are checked.

 CALL:        result = eq(c1,c2)
              result = eq(c1,c2,  exc_list)
              result = eq(c1,c2, 'property1', 'property2')
              result = eq(c1,c2, 'class/property', 'class/property')

 EXAMPLES:    result = eq(c1,c2, 'name', 'created')
              result = eq(c1,c2, 'ao/name')

 INPUTS:      c1,c2    - input cdata objects
              exc_list - exception list
                         List of properties which are not checked.

 OUTPUTS:     If the two cdata objects are considered equal, result == 1,
              otherwise, result == 0.
