NAME
       zsymm.f -

SYNOPSIS
   Functions/Subroutines
       subroutine zsymm (SIDE, UPLO, M, N, ALPHA, A, LDA, B, LDB, BETA, C, LDC)
	   ZSYMM

Function/Subroutine Documentation
   subroutine zsymm (characterSIDE, characterUPLO, integerM, integerN, complex*16ALPHA,
       complex*16, dimension(lda,*)A, integerLDA, complex*16, dimension(ldb,*)B, integerLDB,
       complex*16BETA, complex*16, dimension(ldc,*)C, integerLDC)
       ZSYMM Purpose:

	    ZSYMM  performs one of the matrix-matrix operations

	       C := alpha*A*B + beta*C,

	    or

	       C := alpha*B*A + beta*C,

	    where  alpha and beta are scalars, A is a symmetric matrix and  B and
	    C are m by n matrices.

       Parameters:
	   SIDE

		     SIDE is CHARACTER*1
		      On entry,  SIDE  specifies whether  the  symmetric matrix  A
		      appears on the  left or right  in the  operation as follows:

			 SIDE = 'L' or 'l'   C := alpha*A*B + beta*C,

			 SIDE = 'R' or 'r'   C := alpha*B*A + beta*C,

	   UPLO

		     UPLO is CHARACTER*1
		      On  entry,   UPLO  specifies  whether  the  upper  or  lower
		      triangular  part	of  the  symmetric  matrix   A	is  to	be
		      referenced as follows:

			 UPLO = 'U' or 'u'   Only the upper triangular part of the
					     symmetric matrix is to be referenced.

			 UPLO = 'L' or 'l'   Only the lower triangular part of the
					     symmetric matrix is to be referenced.

	   M

		     M is INTEGER
		      On entry,  M  specifies the number of rows of the matrix	C.
		      M  must be at least zero.

	   N

		     N is INTEGER
		      On entry, N specifies the number of columns of the matrix C.
		      N  must be at least zero.

	   ALPHA

		     ALPHA is COMPLEX*16
		      On entry, ALPHA specifies the scalar alpha.

	   A

		     A is COMPLEX*16 array of DIMENSION ( LDA, ka ), where ka is
		      m  when  SIDE = 'L' or 'l'  and is n  otherwise.
		      Before entry  with  SIDE = 'L' or 'l',  the  m by m  part of
		      the array  A  must contain the  symmetric matrix,  such that
		      when  UPLO = 'U' or 'u', the leading m by m upper triangular
		      part of the array  A  must contain the upper triangular part
		      of the  symmetric matrix and the	strictly  lower triangular
		      part of  A  is not referenced,  and when	UPLO = 'L' or 'l',
		      the leading  m by m  lower triangular part  of the  array  A
		      must  contain  the  lower triangular part  of the  symmetric
		      matrix and the  strictly upper triangular part of  A  is not
		      referenced.
		      Before entry  with  SIDE = 'R' or 'r',  the  n by n  part of
		      the array  A  must contain the  symmetric matrix,  such that
		      when  UPLO = 'U' or 'u', the leading n by n upper triangular
		      part of the array  A  must contain the upper triangular part
		      of the  symmetric matrix and the	strictly  lower triangular
		      part of  A  is not referenced,  and when	UPLO = 'L' or 'l',
		      the leading  n by n  lower triangular part  of the  array  A
		      must  contain  the  lower triangular part  of the  symmetric
		      matrix and the  strictly upper triangular part of  A  is not
		      referenced.

	   LDA

		     LDA is INTEGER
		      On entry, LDA specifies the first dimension of A as declared
		      in the  calling (sub) program. When  SIDE = 'L' or 'l'  then
		      LDA must be at least  max( 1, m ), otherwise  LDA must be at
		      least max( 1, n ).

	   B

		     B is COMPLEX*16 array of DIMENSION ( LDB, n ).
		      Before entry, the leading  m by n part of the array  B  must
		      contain the matrix B.

	   LDB

		     LDB is INTEGER
		      On entry, LDB specifies the first dimension of B as declared
		      in  the  calling	(sub)  program.   LDB  must  be  at  least
		      max( 1, m ).

	   BETA

		     BETA is COMPLEX*16
		      On entry,  BETA  specifies the scalar  beta.  When  BETA	is
		      supplied as zero then C need not be set on input.

	   C

		     C is COMPLEX*16 array of DIMENSION ( LDC, n ).
		      Before entry, the leading  m by n  part of the array  C must
		      contain the matrix  C,  except when  beta  is zero, in which
		      case C need not be set on entry.
		      On exit, the array  C  is overwritten by the  m by n updated
		      matrix.

	   LDC

		     LDC is INTEGER
		      On entry, LDC specifies the first dimension of C as declared
		      in  the  calling	(sub)  program.   LDC  must  be  at  least
		      max( 1, m ).
