CentOS 7.0 - man page for cgetrs (centos section 3)

cgetrs.f(3)				      LAPACK				      cgetrs.f(3)

NAME
       cgetrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine cgetrs (TRANS, N, NRHS, A, LDA, IPIV, B, LDB, INFO)
	   CGETRS

Function/Subroutine Documentation
   subroutine cgetrs (characterTRANS, integerN, integerNRHS, complex, dimension( lda, * )A,
       integerLDA, integer, dimension( * )IPIV, complex, dimension( ldb, * )B, integerLDB,
       integerINFO)
       CGETRS

       Purpose:

	    CGETRS solves a system of linear equations
	       A * X = B,  A**T * X = B,  or  A**H * X = B
	    with a general N-by-N matrix A using the LU factorization computed
	    by CGETRF.

       Parameters:
	   TRANS

		     TRANS is CHARACTER*1
		     Specifies the form of the system of equations:
		     = 'N':  A * X = B	   (No transpose)
		     = 'T':  A**T * X = B  (Transpose)
		     = 'C':  A**H * X = B  (Conjugate transpose)

	   N

		     N is INTEGER
		     The order of the matrix A.  N >= 0.

	   NRHS

		     NRHS is INTEGER
		     The number of right hand sides, i.e., the number of columns
		     of the matrix B.  NRHS >= 0.

	   A

		     A is COMPLEX array, dimension (LDA,N)
		     The factors L and U from the factorization A = P*L*U
		     as computed by CGETRF.

	   LDA

		     LDA is INTEGER
		     The leading dimension of the array A.  LDA >= max(1,N).

	   IPIV

		     IPIV is INTEGER array, dimension (N)
		     The pivot indices from CGETRF; for 1<=i<=N, row i of the
		     matrix was interchanged with row IPIV(i).

	   B

		     B is COMPLEX array, dimension (LDB,NRHS)
		     On entry, the right hand side matrix B.
		     On exit, the solution matrix X.

	   LDB

		     LDB is INTEGER
		     The leading dimension of the array B.  LDB >= max(1,N).

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
