Hello,
DoubleVector is the wrong type; it should be Array (truth be told,
I'm not sure how SWIG allows you to pass it at all; it should give a
type error).
Anyway: you can use the right type, but it's also possible to pass
lists directly. Code like
from QuantLib import *
a = [1,2,3,4,5]
b = [11,12,13,14,15]
e = LinearInterpolation(a,b)
will work without forcing the types. As for BicubicSplines, it doesn't
want iterators. It's a 2-d interpolation, so the three arguments
should be the array of the x, the array of the y, and the matrix of
the corresponding z defined so that z[i][j] = f(x[i], y[j]). Again, no
need to force the types: you can write
x = [1,2,3]
y = [1,2]
z = [[1,2,3],
[4,5,6]]
f = BicubicSpline(x,y,z)
