My output did not display in command windows when using script

hello, I have a problem where my output did not display in command windows when i have run in script ,what should i do? my coding can run but did not display in command windows.

This below my coding

fid = fopen('abc.txt','w');
vol=zeros(6,4);
Percentage=zeros(6,4);

Vact= [31.06300,40.29600,49.52700,58.75800;
      6.209400,8.057700,9.904700,11.75130;
      0.306610,0.401110,0.494380,0.587210;
      0.073430,0.098860,0.122920,0.146530;
      0.039958,0.055665,0.069856,0.083571;
      0.026436,0.038378,0.048629,0.058391];

P = [0.01,0.05,1,4,7,10];
T = [673.15,873.15,1073.15,1273.15];

	
for i=1:6
  for j=1:4
  vol(i,j) = ((0.000461631).*T(j))./P(i);
  end
end

% Calculate %error
	
for i=1:6
  for j=1:4
    Percentage(i,j) = 100.0*(vol(i,j)-Vact(i,j))/Vact(i,j);
  end
end

% Table header estimated z

fprintf(fid,'Estimated z');
fprintf(fid,'\n              2       4       6\n');
fprintf(fid,' ---------------------------------\n');

% Print estimated z table

for i=1:6
  fprintf(fid,' | %6.2f | %6.5f %6.5f %6.5f %6.5f | \n',P(i), vol(i,1), vol(i,2), vol(i,3), vol(i,4));
end

% Table header % error

fprintf(fid,'\nEstimated errors');
fprintf(fid,'\n              2       4       6\n');
fprintf(fid,' ---------------------------------\n');
	    
% Percentage error table

for i=1:6
  fprintf(fid,' | %6.2f | %6.2f %6.2f %6.2f %6.2f | \n',P(i), Percentage(i,1), Percentage(i,2), Percentage(i,3), Percentage(i,4));
end

fclose(fid);

This below showed my screen that command windows give me only the name of my file

Your code seems to be behaving as expected: there appears to be no commands that would print to the command window and you have semi-colons at the end of each line. Why do you expect something to be printed in the command window?

Tip: when opening a text file you should use the t option, e.g.:

fid = fopen('abc.txt','wt');

[the cyclist]

The syntax you used,

fprintf(fid,...)

is explicitly for writing to files. Use

fprintf(...) % without "fid" argument

to write to the command window instead.

The first input can also be 1 to print to the command window.

fprintf(1, ...)

or 2 to print to the command window in red

fprintf(2, ...)

but most commonly, the syntax recommended by the cyclist is used.
