@ the cyclist :
Hope xlwrite will help you. Thank you for the remark about the specific cells export. I didn't focus on this point yet. The idea behind xlwrite was to export Matlab 3d arrays of doubles or cells to excel.
If time permits, my next submission will contain currently missing xlswrite features.
Complicated to get started with the java files etc and no very good instructions on this. See the example however.
Doesn't support specifying to a range.
However - support multi-dimensional variables which is a great bonus.
