How about delaunay?

load seamount
tri = delaunay(x,y);
trisurf(tri,x,y,z);

Use readtable() to read in your data into x,y,z arrays. If you have a really old version of MATLAB, use csvread(), textscan(), or similar.

Hi, thank you for the answer. Excuse me if I asked you this: if I have a file, and in each row I have 3 values as the example, where I am supposed to put my values in your code? Thank you

Use readtable() to read in your data into x,y,z arrays. If you have a really old version of MATLAB, use csvread(), textscan(), or similar. But haven't you already done that? I would think so since somehow you plotted some stuff.
