/* 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). */
