numpy.polydiv
-
numpy.polydiv(u, v)
[source] -
Returns the quotient and remainder of polynomial division.
The input arrays are the coefficients (including any coefficients equal to zero) of the “numerator” (dividend) and “denominator” (divisor) polynomials, respectively.
- Parameters
-
-
uarray_like or poly1d
-
Dividend polynomial’s coefficients.
-
varray_like or poly1d
-
Divisor polynomial’s coefficients.
-
- Returns
-
-
qndarray
-
Coefficients, including those equal to zero, of the quotient.
-
rndarray
-
Coefficients, including those equal to zero, of the remainder.
-
Notes
Both
u
andv
must be 0-d or 1-d (ndim = 0 or 1), butu.ndim
need not equalv.ndim
. In other words, all four possible combinations -u.ndim = v.ndim = 0
,u.ndim = v.ndim = 1
,u.ndim = 1, v.ndim = 0
, andu.ndim = 0, v.ndim = 1
- work.Examples
>>> x = np.array([3.0, 5.0, 2.0]) >>> y = np.array([2.0, 1.0]) >>> np.polydiv(x, y) (array([1.5 , 1.75]), array([0.25]))
