CGERC

Function/Subroutine Documentation

  subroutine cgerc (integerM, integerN, complexALPHA, complex, dimension(*)X, integerINCX, complex, dimension(*)Y, integerINCY, complex, dimension(lda,*)A, integerLDA)

CGERC Purpose:

     CGERC  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
               On entry, ALPHA specifies the scalar alpha.

    X

              X is COMPLEX array of 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 array of 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 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

              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 ).
