zlag2c

zlag2c.f(3)							      LAPACK							       zlag2c.f(3)

NAME

       zlag2c.f -

SYNOPSIS

   Functions/Subroutines
       subroutine zlag2c (M, N, A, LDA, SA, LDSA, INFO)
	   ZLAG2C converts a complex double precision matrix to a complex single precision matrix.

Function/Subroutine Documentation
   subroutine zlag2c (integerM, integerN, complex*16, dimension( lda, * )A, integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO)
       ZLAG2C converts a complex double precision matrix to a complex single precision matrix.

       Purpose:

	    ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A.

	    RMAX is the overflow for the SINGLE PRECISION arithmetic
	    ZLAG2C checks that all the entries of A are between -RMAX and
	    RMAX. If not the convertion is aborted and a flag is raised.

	    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.

	   A

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

	   LDA

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

	   SA

		     SA is COMPLEX array, dimension (LDSA,N)
		     On exit, if INFO=0, the M-by-N coefficient matrix SA; if
		     INFO>0, the content of SA is unspecified.

	   LDSA

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

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit.
		     = 1:  an entry of the matrix A is greater than the SINGLE
			   PRECISION overflow threshold, in this case, the content
			   of SA in exit is unspecified.
