Class Sgesv

      org.netlib.lapack.Sgesv

    public class Sgesv

extends java.lang.Object

    Following is the description from the original
    Fortran source.  For each array argument, the Java
    version will include an integer offset parameter, so
    the arguments may not match the description exactly.

     *  Purpose
     *  =======
     *
     *  SGESV computes the solution to a real 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 LU decomposition with partial pivoting and row interchanges is
     *  used to factor A as
     *     A = P * L * U,
     *  where P is a permutation matrix, L is unit lower triangular, and U is
     *  upper triangular.  The factored form of A is then used to solve the
     *  system of equations A * X = B.
     *
     *  Arguments
     *  =========
     *
     *  N       (input) INTEGER
     *          The number of linear equations, i.e., the order of the
     *          matrix A.  N >= 0.
     *
     *  NRHS    (input) INTEGER
     *          The number of right hand sides, i.e., the number of columns
     *          of the matrix B.  NRHS >= 0.
     *
     *  A       (input/output) REAL array, dimension (LDA,N)
     *          On entry, the N-by-N coefficient matrix A.
     *          On exit, the factors L and U from the factorization
     *          A = P*L*U; the unit diagonal elements of L are not stored.
     *
     *  LDA     (input) INTEGER
     *          The leading dimension of the array A.  LDA >= max(1,N).
     *
     *  IPIV    (output) INTEGER array, dimension (N)
     *          The pivot indices that define the permutation matrix P;
     *          row i of the matrix was interchanged with row IPIV(i).
     *
     *  B       (input/output) REAL array, dimension (LDB,NRHS)
     *          On entry, the N-by-NRHS matrix of right hand side matrix B.
     *          On exit, if INFO = 0, the N-by-NRHS solution matrix X.
     *
     *  LDB     (input) INTEGER
     *          The leading dimension of the array B.  LDB >= max(1,N).
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit
     *          < 0:  if INFO = -i, the i-th argument had an illegal value
     *          > 0:  if INFO = 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.
     *
