Hye guyz. I need some help here. I have this coding:

    fileName = inputdlg('Please enter the name for your figures');
    directoryName = uigetdir('','Please select a folder to save to');
    if directoryName == 0      %# User pressed the "Cancel" button...
    directoryName = '';      %#   ...so choose the empty string for the folder
    end
    filePath = fullfile(directoryName,fileName{1});  %# Create the file path
    extensions = {'fig','bmp'};
    for k = 1:length(extensions)
      saveas(gcf,filePath,extensions{k});  %# Save the file
      set(gcf,'PaperPositionMode','auto');
    end

This coding have some problem. When i run this coding, it occurs this error:

??? Index exceeds matrix dimensions.

Error in ==> fyp_editor>uipushtool9_ClickedCallback at 1607 filePath = fullfile(directoryName,fileName{1}); %# Create the file path.

And another thing is when i pressed the cancel button, it kkeep going to filepath. How i want to do something like; when i push the cancel, then it will cancel the save program.

Another way, might be better because the return function can have undesirable consequences.

 fileName = inputdlg('Please enter the name for your figures');
    directoryName = uigetdir('','Please select a folder to save to');
    if directoryName == 0      %# User pressed the "Cancel" button...
    directoryName = '';      %#   ...so choose the empty string for the folder
    else
    filePath = fullfile(directoryName,fileName{1});  %# Create the file path
    extensions = {'fig','bmp'};
    for k = 1:length(extensions)
      saveas(gcf,filePath,extensions{k});  %# Save the file
      set(gcf,'PaperPositionMode','auto');
    end
end

how about if i want to cancel the inputdlg then it will do nothing and end the save program.

i think i already solve it by writing this code:

if isempty(fileName)

return

end

Thanks in advance
