% Calculate the minimum weight or distance of a linear block code. The
% code can be either defined by its generator or parity check matrix, or
% its generator polynomial. By default if the first argument is a matrix,
% it is assumed to be the generator matrix of the code. The type of the
% matrix can be defined by a flag 'gen' for the generator matrix or
% 'par' for the parity check matrix.
%
% If the first argument is a vector, it is assumed that it defines the
% generator polynomial of the code. In this case a second argument is
% required that defines the codeword length.
