Signature

def zgeru(alpha, x, y, incx = 1, incy = 1, a = None, overwrite_x = 0, overwrite_y = 0, overwrite_a = 0)

General rank-1 update a = alpha*outer(x, y) + a (BLAS zgeru).

alpha : complex: Scalar multiplier.
x : ndarray: Input vector of length m.
y : ndarray: Input vector of length n.
incx : int, optional: Stride between successive elements of x. Default is 1.
incy : int, optional: Stride between successive elements of y. Default is 1.
a : ndarray, optional: (m, n) matrix to update; if omitted a new zero matrix is allocated. Default is None.
overwrite_x : int, optional: If nonzero, x may be overwritten in place. Default is 0.
overwrite_y : int, optional: If nonzero, y may be overwritten in place. Default is 0.
overwrite_a : int, optional: If nonzero, a may be overwritten in place. Default is 0.
