I'm trying to set the file name for export_fig as a variable. For instance, I could ask a user what they wanted to save a figure as and then save the figure with their answer. How would I do this?

Additionally, I want to save figures to a specific folder on my computer. What is correct syntax for this?

在 MATLAB Online 中打开

[filename, pathname] = uiputfile( {'*.tif', '*.png', '*.pdf'}, 'Select an output file');
if isnumeric(filename)   %watch out for user cancel
  disp('Canceled!')
else
  fullname = fullfile(pathname, filename);
  [~, ~, ext] = fileparts(fullname);
  opts = {'-a1', '-png'};
  if strcmp(ext, '.pdf'); opts{end+1} = '-pdf'; end
  export_fig(fullname, opts{:});
end
