I am attempting to use the polynomial interpolation method with GSL. However I
am getting very strange results.

If I run the attached program I get the below result. If I change the method
to linear or cspline the interpolation works fine.

Not in previous gsl versions the polynomial interpolation has worked!

Is there something I am missing?

Yours aye
