# MATLAB: How to edit and save xyz format data

edit xyz data

Hello, I replace some value in z column (ex: -0,01 become 0) and plot it. But it seems not all data are replaced well. After that, how to save it to a new XYZ file, so I can make a comparison. The script that I use :
function tes_replace  A  = load('no_river.txt'); A(A(:,3)==-0.01,3)=0;  x = A (:,1); y = A (:,2) ; z = A(:,3); scatter (x,y,10,z,'filled')colorbarcaxis ([-0.01 0])

% function tes_replaceA  = load('no_river.txt');x = A (:,1); y = A (:,2) ; z = A(:,3);% z(z==-0.01)=0;idx = abs(z-(-0.01))<10^-3 ;z(idx) = 0 ;scatter (x,y,10,z,'filled')colorbarcaxis ([-0.01 0])
