subroutine zgerc (M, N, ALPHA, X, INCX, Y, INCY, A, LDA)
subroutine zgerc (integerM, integerN, complex*16ALPHA, complex*16, dimension(*)X, integerINCX, complex*16, dimension(*)Y, integerINCY, complex*16, dimension(lda,*)A, integerLDA)
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.
M is INTEGER On entry, M specifies the number of rows of the matrix A. M must be at least zero.
N is INTEGER On entry, N specifies the number of columns of the matrix A. N must be at least zero.
ALPHA is COMPLEX*16 On entry, ALPHA specifies the scalar alpha.
X is 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.
INCX is INTEGER On entry, INCX specifies the increment for the elements of X. INCX must not be zero.
Y is 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.
INCY is INTEGER On entry, INCY specifies the increment for the elements of Y. INCY must not be zero.
A is 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 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 ).
