Simple xlswrite question.

Hello,

I have a few matrices that I want to export in excel. Every time I run my code, I want to export few outputs in Excel. From what i've found I have to hardcode the file name, by doing that I am always writing in the same file. I need to find a way to always create a new file or clear the content of the same file before writing in it.

Thanks

Try uiputfile() and let the user specify the name by typing it in:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath % Or "pwd" or wherever you want.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)

Or you can create the filename from values of some of your variables if you use sprintf().
