how to generate text file from generated output

A={{},{0 0;1 2;3 4;NaN NaN},{0 0;5 6;7 8;9 10;NaN NaN},{0 0;11 12;13 14;15 16;17 18;19 20;NaN NaN},{0 0;21 22;NaN NaN}};
   SH = -.3;
   n=450;
   k=0;
   s=size(A,2);
   fprintf('%s%5.2f%s%5.2f%s%5.2f\n',T_11,A{1,2}{2,1},T_12,A{1,2}{2,2},T_13,(k))
   
   for j=2:1:s
       for i=2:1:(size(A{1,j},1)-1)
       fprintf('%s%5.2f%s%5.2f%s%5.2f\n',T_11,A{1,j}{i,1},T_12,A{1,j}{i,2},T_13,SH*j-SH)
       n=n+10;
       end
       j=j+1;
   end

Above code gives output which is written below:

X 1.00Y 2.00Z 0.00

X 1.00Y 2.00Z-0.30

X 3.00Y 4.00Z-0.30

X 5.00Y 6.00Z-0.60

X 7.00Y 8.00Z-0.60

X 9.00Y10.00Z-0.60

X11.00Y12.00Z-0.90

X13.00Y14.00Z-0.90

X15.00Y16.00Z-0.90

X17.00Y18.00Z-0.90

X19.00Y20.00Z-0.90

X21.00Y22.00Z-1.20

I have to convert this output into a text file with .gcd extension how can I create ?

fprintf() accepts as 1st argument a file identifier for a file opened with fopen().

fid = fopen("somefile","w")

fprintf(fid,"mytext")

fclose(fid)
