NAME
SRC/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 (integer m, integer n, complex*16, dimension( lda, * ) a, integer lda, complex, dimension( ldsa, * ) sa, integer ldsa, integer info)

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 conversion 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.
