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 (integer M, integer N, complex, dimension( ldsa, * ) SA, integer LDSA,
       complex*16, dimension( lda, * ) A, integer LDA, integer INFO)
       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
