numpy.polynomial.hermite_e.hermesub(c1, c2)
[source] -
Subtract one Hermite series from another.
Returns the difference of two Hermite series
c1
-c2
. The sequences of coefficients are from lowest order term to highest, i.e., [1,2,3] represents the seriesP_0 + 2*P_1 + 3*P_2
.Parameters: c1, c2 : array_like
1-D arrays of Hermite series coefficients ordered from low to high.
Returns: out : ndarray
Of Hermite series coefficients representing their difference.
Notes
Unlike multiplication, division, etc., the difference of two Hermite series is a Hermite series (without having to ?reproject? the result onto the basis set) so subtraction, just like that of ?standard? polynomials, is simply ?component-wise.?
Examples
>>> from numpy.polynomial.hermite_e import hermesub >>> hermesub([1, 2, 3, 4], [1, 2, 3]) array([ 0., 0., 0., 4.])
