clag2z

clag2z.f(3)							      LAPACK							       clag2z.f(3)

NAME

       clag2z.f -

SYNOPSIS

   Functions/Subroutines
       subroutine clag2z (M, N, SA, LDSA, A, LDA, INFO)
	   CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

Function/Subroutine Documentation
   subroutine clag2z (integerM, integerN, complex, dimension( ldsa, * )SA, integerLDSA, complex*16, dimension( lda, * )A, integerLDA, integerINFO)
       CLAG2Z converts a complex single precision matrix to a complex double precision matrix.

       Purpose:

	    CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A.

	    Note that while it is possible to overflow while converting
	    from double to single, it is not possible to overflow when
	    converting from single to double.

	    This is an auxiliary routine so there is no argument checking.

       Parameters:
	   M

		     M is INTEGER
		     The number of lines of the matrix A.  M >= 0.

	   N

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

	   SA

		     SA is COMPLEX array, dimension (LDSA,N)
		     On entry, the M-by-N coefficient matrix SA.

	   LDSA

		     LDSA is INTEGER
		     The leading dimension of the array SA.  LDSA >= max(1,M).

	   A

		     A is COMPLEX*16 array, dimension (LDA,N)
		     On exit, the M-by-N coefficient matrix A.

	   LDA

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

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
