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: |
u : array_like or poly1d Dividend polynomial’s coefficients. v : array_like or poly1d Divisor polynomial’s coefficients. |
---|---|
Returns: |
q : ndarray Coefficients, including those equal to zero, of the quotient. r : ndarray Coefficients, including those equal to zero, of the remainder. |
Both u
and v
must be 0-d or 1-d (ndim = 0 or 1), but u.ndim
need not equal v.ndim
. In other words, all four possible combinations - u.ndim = v.ndim = 0
, u.ndim = v.ndim = 1
, u.ndim = 1, v.ndim = 0
, and u.ndim = 0, v.ndim = 1
- work.
>>> 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]))
