numpy.polynomial.legendre.legsub()

numpy.polynomial.legendre.legsub

numpy.polynomial.legendre.legsub(c1, c2) [source]

Subtract one Legendre series from another.

Returns the difference of two Legendre 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, c2 : array_like

1-D arrays of Legendre series coeffic
