ScientificErrorAnalysis

 GetStructure
 return the interface of an available quantity-with-error structure

 Calling Sequence GetStructure( struct )

Parameters

 struct - type; type of an available quantity-with-error structure

Description

 • The GetStructure( struct ) command returns the three interface procedures of the quantity-with-error structure of type struct.
 • The three interface procedures are returned in an expression sequence.
 The first item is the procedure that returns the central value of a quantity-with-error of type struct.
 The second item is the procedure that returns the absolute uncertainty of a quantity-with-error of type struct.
 The third item is the procedure that returns the identifier of a quantity-with-error of type struct.
