Approximate integration of a B-Spline kernel product

\[ \int_{x_0}^L \frac{\partial^{d_1}}{\partial x^{d_1}} \beta(x - s_1) \frac{\partial^{d_2}}{\partial x^{d_2}} \beta(x - s_2) dx \]

using the Simpson integration.

Parameters

spline	kernel \(\beta\)
s1
s2
d1
d2
n	number of integration intervals
x0	start of interval
L	end of interval

Returns

value of integral
