numpy.polynomial.hermite_e.hermesub

polynomial.hermite_e.hermesub(c1, c2)

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 series P_0 + 2*P_1 + 3*P_2.

Parameters:

c1, c2array_like

1-D arrays of Hermite series coefficients ordered from low to high.

Returns:

outndarray

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.」
