<p>PURPOSE:To accurately obtain even a long active vector <d> that functions to secure the matching between the 1st and 2nd functions f1 and f2 of a vector <x>. CONSTITUTION:The partial differentialtion filter circuits 3-0-3-K obtain the partial differential functions of various degrees in regard of each element xi of both functions f1 and f2. The error detecting circuits 4-0-4-K obtain the matching error equal to a square of the absolute value of the difference from the primary Taylor series expansion in regard of the active vector <d> of the partial differential function computing circuits 5, 7-0-7-K, 8 and 9 obtain the evaluation function B(<x>, <d>) by adding an additional condition formula to the weighted sum of the matching errors of various degrees. Then a control circuit 6 decides the valve of the active vector <d> so that the value of the function B is minimized.</p> |
