Locations=[1 2 ; 2 3 ; 4 5];
P1=[1 2 3];
input= [3 4 5]
fid= fopen('GCode.txt','w');
for x = P1(1) : P1(end)
        fprintf(fid,'G0 X%d Y%d Z0 \n',Locations(x,1),Locations(x,2));
        for y = 1:input(x);
        fprintf(fid,'G0 Z1 \n G0 Z0');
        end    
end
fclose(fid);

I would like to output every location into a .txt file in a list as well as a reapeting string as many times as the value in the location in the input vector. Output I want: Iteration 1:

G0 X1 Y2 Z0 G0 Z1 G0 Z0

G0 Z1 G0 Z0

Iteration 2:

G0 X2 Y3 Z0 G0 Z1 G0 Z0

G0 Z1 G0 Z0

Iteration 3:

G0 X4 Y5 Z0 G0 Z1 G0 Z0

G0 Z1 G0 Z0

However when running this code, it only outputs the final iteration of the for loop instead of the result of every iteration in a list to the .txt file. Any help would be greatly appreciated. (The purpose of this code is to automatically generate G-Codes for a CNC machine based upon input X Y coordinates)

I guess you didn't notice that he used input for an variable name. It should be replaced with a non-reserved word like in my code below. Plus, this should have been an answer, not a comment, so you could get credit for it.

Oops, guess my eyes are a little too strained to catch that. My bad

This code will do that:

Locations=[1 2 ; 2 3 ; 4 5]
P1=[1 2 3];
repeatCount = [3 4 5]
% fid= fopen('GCode.txt','w');
fid=1; % To command window for testing.
for x = P1(1) : P1(end)
  fprintf(fid,'G0 X%d Y%d Z0 G0 Z1 G0 Z0\n',Locations(x,1),Locations(x,2));
  for y = 1 : (repeatCount(x) - 1);
    fprintf(fid,'G0 Z1 G0 Z0\n');
  end
end
% fclose(fid);
