-/* The CloogMatrix structure is equivalent to the PolyLib Matrix data structure
- * (see Wil93). This structure is devoted to represent a set of constraints.
- *
- * The whole matrix is stored in memory row after row at the p_Init address. p
- * is an array of pointers where p[i] points to the first element of the i^{th
- * row. NbRows and NbColumns are respectively the number of rows and columns of
- * the matrix. Each row corresponds to a constraint. The first element of each
- * row is an equality/inequality tag. The constraint is an equality p(x) = 0 if
- * the first element is 0, but it is an inequality p(x) \geq 0 if the first
- * element is 1. The next elements are the unknown coefficients, followed by
- * the parameter coefficients, then the constant term. For instance, the
- * following three constraints:
- *
- * -i + m = 0
- * -j + n >= 0
- * i + j - k >= 0
- *
- * would be represented by the following rows:
- *
- * # eq/in i j k m n cst
- * 0 0 -1 0 1 0 0
- * 1 -1 0 0 0 1 0
- * 1 1 1 -1 0 0 0
- *
- * To be able to provide different precision version (CLooG supports 32 bits,
- * 64 bits and arbitrary precision through the GMP library), the cloog_int_t
- * type depends on the configuration options (it may be long int for 32 bits
- * version, long long int for 64 bits version, and mpz_t for multiple precision
- * version). */
