Structure for equations.

Field Documentation

int* eqn_d::coef

Array of coefficients for the equation. The layout of the data is as follows: coef[0] is the constant, coef[i] for 1 <= i <= OMEGA_MAX_VARS, are the coefficients for each dimension. Examples: the equation 0 = 9 + x + 0y + 5z is encoded as [9 1 0 5], the inequality 0 <= -8 + x + 2y + 3z is encoded as [-8 1 2 3].
