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.
