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 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.
