@Yair – I have to reword my previous comment :
Alec de Zegher published a utility http://www.mathworks.com/matlabcentral/fileexchange/38591 (also named ‘xlwrite’) and uses exact syntax as xlswrite. It is an excellent work (use of JExcelApi only).
In contrast, my original submission uses JExcelAPI and MXL package (that I’ve coded to handle 2d/3d data ).

This is why in my previous comment I pointed out to Alec’s excellent submission : same syntax as in xlswrite. However, Alec’s xlwrite handles 2d data only.
It seems to me that Mac/Linux/Unix MATLAB users will soon get xlswrite and xlsread full adaptations!
Have a good day all!

@Marin – I believe that @cyclist was only trying to say that although your xlwrite utility is great, it does not have the exact same inputs format as xlswrite. If you could make xlwrite use exactly the same inputs format as xlswrite, then it will be much easier for users to use xlwrite.

@ the cyclist:
check the following submission:

@Jamy – I suggest leaving a comment for Marin Deresco on his xlwrite‘s FEX page.

Cheers,
J.

@Cyclist – thanks for the catch. I updated the wording accordingly.

One caveat, though. Unless I am misunderstanding something, it is not 100% accurate to say that the inputs are the same as those of xlswrite. In particular, it doesn’t seem that xlwrite will accept the “range” argument, that allows the user to specify where on the worksheet to write the array.

@Frank – thanks. You’re right of course – I’ve known POI for several years so I don’t know why I forgot to mention it in the article… It’s now taken its rightful place in the article text.
