D.10.1.9 decodeSV

Procedure from library brnoeth.lib (see brnoeth_lib).

Usage:
decodeSV( y, K ); y a row-matrix and K a list

Return:
a codeword (row-matrix) if possible, resp. the 0-matrix (of size 1) if decoding is impossible.
For decoding the basic (Skorobogatov-Vladut) decoding algorithm is applied.

Note:
The list_expression should be the output K of the procedure prepSV.
The matrix_expression should be a (1 x n)-matrix, where n = ncols(K[1]).
The decoding may fail if the number of errors is greater than the correction capacity of the algorithm.

Example:
