Matlab Apps for Two-Dimensional Interpolation functions from scattered points (xyz), i.e., Linear, Nearest neighbor, Natural neighbor, Cubic, and Spline interpolation.
Read and export data sets in ASCII cloud format (.txt,.asc,.xyz,.pts,*.csv).
Tuneable output grid interval in meter (in a uniform grid).
Option to make extrapolation.
Created with App Designer and Matlab 2019b libraries.
