CLAG2Z(3)      LAPACK routine of NEC Numeric Library Collection      CLAG2Z(3)



NAME
       CLAG2Z

SYNOPSIS
       SUBROUTINE CLAG2Z (M, N, SA, LDSA, A, LDA, INFO)



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.




ARGUMENTS
           M         (input)
                     M is INTEGER
                     The number of lines of the matrix A.  M >= 0.

           N         (input)
                     N is INTEGER
                     The number of columns of the matrix A.  N >= 0.

           SA        (input)
                     SA is COMPLEX array, dimension (LDSA,N)
                     On entry, the M-by-N coefficient matrix SA.

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

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

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

           INFO      (output)
                     INFO is INTEGER
                     = 0:  successful exit
