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.
