Are there any interpolation functions in the PyNGL module?
A few interpolation functions have been included in the PyNGL module, primarily in support of the examples. The 1-dimensions tension spline interpolator Ngl.ftcurv is used in tutorial example 11. The 1-dimensional tension spline interpolator for periodic data Ngl.ftcurvp is used in tutorial example 7. The 1-dimensional integral calculator for periodic data Ngl.ftcurvpi is used in tutorial example 7. The 2-dimensional interpolator for random data Ngl.natgrid is used in tutorial example 8.
