I want to interpolate 3d scatter. i have a code and want to add for interpolation.
code is down here.
<<data = importdata('20200211MOHANG_group1_densified_point_cloud.txt');
x = data(:,1);
y = data(:,2);
z = data(:,3);
i hope to use 'interp2' and 'griddata', but i don't know how to use.
Thank you very much if you can modify that code by adding 'interp2' or 'griddata' or both.

I would assume interp3 is more relevant since you have 3d data to initerpolate.

Use ‘scatteredInterpolant’ function to interpolate the 3d scattered data. The 3d scattered data can also be interpolated using Delaunay triangulation of the points.
