MATLAB: Translation matrix in OXY plane

.

Let's say: I have matrix A=[x y z] with ~3.000 point data . Please see attachment file, and figure:
My question is: how can I translate all points with distance 1 in the black arrow direction (// with the long edge of the points), as illustrate figure?

You need to add that value to the coordinates. If you want to move along x-axes add 1 unit to x coordinates.
data = importdata('A.txt') ;
x = data(:,1) ; 
y = data(:,2) ; 
z = data(:,3) ; 
plot3(x,y,z,'.r')
hold on
%% Translate along x axis by unit 1
dx = 1. ;
x = x+dx ; 
plot3(x,y,z,'.b')
