zgerc performs the rank 1 operation A := alpha*x*conjg( y' )
+ 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 (input)
On entry, M specifies the number of rows of the
matrix A. M >= 0. Unchanged on exit.
N (input)
On entry, N specifies the number of columns of the
matrix A. N >= 0. Unchanged on exit.
ALPHA (input)
On entry, ALPHA specifies the scalar alpha.
Unchanged on exit.
X (input)
( 1 + ( m - 1 )*abs( INCX ) ). Before entry, the
incremented array X must contain the m element
vector x. Unchanged on exit.
INCX (input)
On entry, INCX specifies the increment for the
elements of X. INCX must not be zero. Unchanged
on exit.
Y (input)
( 1 + ( n - 1 )*abs( INCY ) ). Before entry, the
incremented array Y must contain the n element
vector y. Unchanged on exit.
INCY (input)
On entry, INCY specifies the increment for the
elements of Y. INCY must not be zero. Unchanged
on exit.
A (input/output)
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 (input)
On entry, LDA specifies the first dimension of A
as declared in the calling (sub) program. LDA >=
max( 1, m ). Unchanged on exit.
