| Each line describes one linear inequality. The encoding is as follows: (a_0,a_1,...,a_d) is the inequality a_0 + a_1 x_1 + ... + a_d x_d >= 0. This way a point in homogeneous coordinates satisfies an inequality if and only if the scalar product of the point with the inequality gives a non-negative value. (Use the command ''print_constraints($m)'' to display the inequalities of the matrix ''$m'' in a nice way.) | Each line describes one linear inequality.
