D.10.2.17 sysFL

Procedure from library decodegb.lib (see decodegb_lib).

Usage:
sysFL (check,y,t,e,s); check,y matrix, t,e,s int
 
          - check is a parity check matrix of the code,
          - y is a received word,
          - t the number of errors to correct,
          - e is the extension degree,
          - s is the dimension of the point for the vanishing ideal

Return:
the system of Fitzgerald-Lax for the given decoding problem

Theory:
Based on 'check' of the given linear code, the procedure constructs the corresponding ideal constructed with a generalization of Cooper's philosophy. For basics of the method Fitzgerald-Lax method.

Example:
