Robert, Something like this? In[1]:= list = Range[15, 1, -1] Out[1]= {15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1} In[2]:= start = 5; step = 2; In[3]:= Take[list, {start, Length[list], step}] Out[3]= {11, 9, 7, 5, 3, 1} Maarten van der Burgt Robert Schuerhuber <robert.schuerhuber at gmx.at> on 23-05-2001 07:54:33 AM cc: Subject: [mg28976] [mg28968] Q: Extract Elements from a List? hi! probably a very easy question, but i couldn't find an answer in the mathematica-book: i need to extract elements from a list, starting th element number x and than taking every yth element, eg: with list={a,b,c,d,e,f,g,h,i,j} start=3; step=2: i'd like to get the list {c,e,g,i}. how can i do this in the easiest way? regards, robert
