ZLAG2C(3)      LAPACK routine of NEC Numeric Library Collection      ZLAG2C(3)



NAME
       ZLAG2C

SYNOPSIS
       SUBROUTINE ZLAG2C (M, N, A, LDA, SA, LDSA, INFO)



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.




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.

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

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

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

           INFO      (output)
                     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.
