Interpolate on irregular grid

[sroener]

Hi,

as far as I understand, CSAPS is able to work with univariate, multivariate (both depending x being 1dimensional) and ND-gridded data.

In my use case, I have an irregular grid with missing values in random positions. Is it possible to use CSAPS on that kind of data?

As an example, would CSAPS work on data generated like in the scipy.griddata example?

If irregular grids don't work, would it be feasible to use NaNs to fill the grid?
