Name matlab figure file differently

Question

I want to print out matlab figure differently and let user to input file name each time. I am using print function which automatically save the name of the function that is define in string. so far I have this. I got this answer from here.

filename = gcf;
print(filename,'myfilename','-dpng','-r30');

which print out the figure with myfilename. I was wondering, is there anyway I can let users to input that string every times it prints out the figure? Always appreciate the help from stack overflow. Thanks

There are a number of ways to do this.

• uiputfile - Uses a real save dialog that would warn in the case of overwriting an existing file etc.

  [fname, pname] = uiputfile('filename.png', 'Please select a file location');
  
  % Make sure the user didn't hit cancel
  if isequal(fname, 0) || isequal(pname, 0)
      return;
  end
  
  % Create the filename
  filename = fullfile(pname, fname);
  
  print(gcf, filename, '-dpng', '-r30');
  

• input - Prompt the user to enter a filename at the command window.

  filename = input('Please enter a filename:');
  print(gcf, filename, '-dpng', '-r30');
  

• inputdlg - opens a GUI prompt for the user to enter the desired filename.

  filename = inputdlg('Please enter a filename');
  print(gcf, filename, '-dpng', '-r30');
  

I would recommend the uiputfile approach, personally
