Hello,

I have a question on these two interpolation methods provided in QuantLib : Linear and Log-linear

How are these two different?   I wrote some own some codes with a linear method to bootstrap a zero curve, and the results seemed to be the same as what I got using the QuantLib Log-linear as the interpolator....

Your help would be appreciated,
Xin
