numpy.polynomial.polynomial.polymul()

numpy.polynomial.polynomial.polymul(c1, c2) [source]

Multiply one polynomial by another.

Returns the product of two polynomials c1 * c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents the polynomial 1 + 2*x + 3*x**2.

Parameters:

Parameters:	c1, c2 : array_like 1-D arrays of coefficients representing a polynomial, relative to the ?standard? basis, and ordered from lowest order term to highest.
Returns:	out : ndarray Of the coefficients of their product.

c1, c2 : array_like

1-D arrays of coefficients representing a polynomial, relative to the ?standard? basis, and ordered from lowest order term to highest.

Returns:

out : ndarray

Of the coefficients of their product.

Examples

>>> from numpy.polynomial import polynomial as P
>>> c1 = (1,2,3)
>>> c2 = (3,2,1)
>>> P.polymul(c1,c2)
array([  3.,   8.,  14.,   8.,   3.])
