Function/Subroutine Documentation

subroutine zgerc (integer M, integer N, complex*16 ALPHA, complex*16, dimension(*) X, integer INCX, complex*16, dimension(*) Y, integer INCY, complex*16, dimension(lda,*) A, integer LDA)

ZGERC

Purpose:

 ZGERC  performs the rank 1 operation

    A := alpha*x*y**H + A,

 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.
Parameters:

M

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

N

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

ALPHA

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

X

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

INCX

          INCX is INTEGER
           On entry, INCX specifies the increment for the elements of
           X. INCX must not be zero.

Y

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

INCY

          INCY is INTEGER
           On entry, INCY specifies the increment for the elements of
           Y. INCY must not be zero.

A

          A is COMPLEX*16 array, 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

          LDA is 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 ).
