Functions/Subroutines
subroutine cgerc (M, N, ALPHA, X, INCX, Y, INCY, A, LDA)
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.
NN is INTEGER On entry, N specifies the number of columns of the matrix A. N must be at least zero.
ALPHAALPHA is COMPLEX On entry, ALPHA specifies the scalar alpha.
XX 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.
INCXINCX is INTEGER On entry, INCX specifies the increment for the elements of X. INCX must not be zero.
YY 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.
INCYINCY is INTEGER On entry, INCY specifies the increment for the elements of Y. INCY must not be zero.
AA 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.
LDALDA 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 ).
