I have data like this one (data: irregular in xyz, no data in the white area):

and would like to resample it using linspace. How can I force linspace to do this within the data range and set outside values to NaN? Otherwise the result will be like this one:

Thanks a lot for each hint,

Use scatteredInterpolant() with the Extrapolation Method set to 'none'

Could you confirm that the data you use to plot the above is scattered?
And is it correct that you want to interpolate only within "connected" regions? So the "islands" should be done separately, and the "holes" are not to be filled? And the area that looks like it might be a wafer, the white gap should not be filled?
What about the small white areas around the black dots?
