Felix, try DeleteCases[ { {2,2}, {3,3}, {} }, {} ] Regards, Chris -----Original Message----- From: Felix Farkas [mailto:farkas at icamail.epfl.ch] To: mathgroup at smc.vnet.net Subject: [mg23903] [mg23880] Appending an element to a list Hello, i do have a problem, which is probably very easy, but i couldn't find a reasonable way to solve it. I would appreciate very much any hint. I have a list of lists. My purpose is to append a new elements to this list. These elements are generated by some function. Sometimes the output of the function is an empty list meaning no element. In this situation Append includes the new element in the list. i would like to avoid this behaviour. ex: In[1]:= d={} Out[1]= {} In[2]:= Append[{{2,2},{3,3}},d] Out[2]:= {{2,2},{3,3},{}} Thanks in advance.
