numpy.polynomial.polynomial.polyadd(c1, c2)
[source] -
Add one polynomial to another.
Returns the sum of two polynomials
c1
+c2
. The arguments are sequences of coefficients from lowest order term to highest, i.e., [1,2,3] represents the polynomial1 + 2*x + 3*x**2
.Parameters: c1, c2 : array_like
1-D arrays of polynomial coefficients ordered from low to high.
Returns: out : ndarray
The coefficient array representing their sum.
Examples
>>> from numpy.polynomial import polynomial as P >>> c1 = (1,2,3) >>> c2 = (3,2,1) >>> sum = P.polyadd(c1,c2); sum array([ 4., 4., 4.]) >>> P.polyval(2, sum) # 4 + 4(2) + 4(2**2) 28.0
