personally, I think these are separate bugs.

1 - xlswrite gets a non-empty filename (his last example did provide a
valid filename), but because the folder doesn't exist it fails to
create the file, produces no error, and returns a 1, which is supposed
to mean a successful write operation.

2 - xlswrite accepts an empty filename... and other strange things ensue.
