hermesub(c1, c2)

Returns the difference of two Hermite series :None:None:`c1` - :None:None:`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 .

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."

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.

Subtract one Hermite series from another.

Examples

>>> from numpy.polynomial.hermite_e import hermesub
... hermesub([1, 2, 3, 4], [1, 2, 3])
array([0., 0., 0., 4.])

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
