Matching Module

Before a match operation at least one sequence must be selected by means of a USE command. Matching is then initiated by the MATCH command. The matching module can act on more than one sequence simultaneously by specifying more than one sequence when INITIATING the matching mode. From this command to the corresponding ENDMATCH command MAD accepts the matching commands listed below. For a mathematical description of the minimisation procedures see [James]. In particular one may do the following:

• Define the sequence(s) the matching module will work on
• Set initial conditions for transfer line matching
• Define constraints
• Define the parameters to be varied
• Match by different methods.

• Enter and Leave Matching Mode
  • MATCH: Initiating the Matching Mode
  • ENDMATCH: Leave Matching Mode
• Define Variable Parameter
  • VARY: Set Parameter to Vary
• Constraint
  • CONSTRAINT: Simple Constraint
  • CONSTRAINT: User Defined Variables
  • WEIGHT: Matching Weights
  • GLOBAL: Global Constraints
  • GWEIGHT: Weights for Global Constraints
• Matching Methods
  • LMDIF: Fast Gradient Minimisation
  • MIGRAD: Gradient Minimisation
  • SIMPLEX: Simplex Minimisation
  • JACOBIAN: Newton Minimisation
• Expression Matching with USE_MACRO
