ZGERC(1)

NAME
LAPACK-3 - performs the rank 1 operation A := alpha*x*y**H + A,

SYNOPSIS

SUBROUTINE ZGERC(M,N,ALPHA,X,INCX,Y,INCY,A,LDA)

DOUBLE
    COMPLEX ALPHA

INTEGER
    INCX,INCY,LDA,M,N

DOUBLE
    COMPLEX A(LDA,*),X(*),Y(*)

PURPOSE
ZGERC performs the rank 1 operation
 where alpha is a scalar, x is an m element vector, y is an n element
 vector and A is an m by n matrix.

ARGUMENTS

M      - INTEGER.
     On entry, M specifies the number of rows of the matrix A.
     M must be at least zero.
     Unchanged on exit.

N      - INTEGER.
     On entry, N specifies the number of columns of the matrix A.
     N must be at least zero.
     Unchanged on exit.

ALPHA  - COMPLEX*16      .
     On entry, ALPHA specifies the scalar alpha.
     Unchanged on exit.

X      - COMPLEX*16       array of dimension at least
     ( 1 + ( m - 1 )*abs( INCX ) ).
     Before entry, the incremented array X must contain the m
     element vector x.
     Unchanged on exit.

INCX   - INTEGER.
     On entry, INCX specifies the increment for the elements of
     X. INCX must not be zero.
     Unchanged on exit.

Y      - COMPLEX*16       array of dimension at least
     ( 1 + ( n - 1 )*abs( INCY ) ).
     Before entry, the incremented array Y must contain the n
     element vector y.
     Unchanged on exit.

INCY   - INTEGER.
     On entry, INCY specifies the increment for the elements of
     Y. INCY must not be zero.
     Unchanged on exit.

A      - COMPLEX*16       array of DIMENSION ( LDA, n ).
     Before entry, the leading m by n part of the array A must
     contain the matrix of coefficients. On exit, A is
     overwritten by the updated matrix.

LDA    - INTEGER.
     On entry, LDA specifies the first dimension of A as declared
     in the calling (sub) program. LDA must be at least
     max( 1, m ).
     Unchanged on exit.
