PLASMA_zgesv - Computes the solution to a system of linear equations A * X = B, where A is an N-by-N matrix and X and B are N-by-NRHS matrices. The tile LU decomposition with partial tile pivoting and row interchanges is used to factor A. The factored form of A is then used to solve the system of equations A * X = B.

Parameters:
[in] N The number of linear equations, i.e., the order of the matrix A. N >= 0.
[in] NRHS The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
[in,out] A On entry, the N-by-N coefficient matrix A. On exit, the tile L and U factors from the factorization (not equivalent to LAPACK).
[in] LDA The leading dimension of the array A. LDA >= max(1,N).
[out] L On exit, auxiliary factorization data, related to the tile L factor, necessary to solve the system of equations.
[out] IPIV On exit, the pivot indices that define the permutations (not equivalent to LAPACK).
[in,out] B On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.
[in] LDB The leading dimension of the array B. LDB >= max(1,N).
Returns:
Return values:
PLASMA_SUCCESS successful exit
<0 if -i, the i-th argument had an illegal value
>0 if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the solution could not be computed.
