Try this: In[1]:= states = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}; In[2]:= stim = {33, 44, 55, 66, 77}; In[3]:= ilist = Range[3, 12, 2] Out[3]= {3, 5, 7, 9, 11} In[4]:= states[[ilist]] = {33, 44, 55, 66, 77}; In[5]:= states Out[5]= {1, 2, 33, 4, 44, 6, 55, 8, 66, 10, 77, 12, 13, 14} Cheers, Vittorio >-----Original Message----- >From: Swati Shah [mailto:swatshah at gmail.com] To: mathgroup at smc.vnet.net >Sent: Thursday, May 12, 2005 8:33 AM >To: mathgroup at smc.vnet.net >Subject: [mg57031] [mg56998] MapThread > >Hi Everyone, > >I have been working on the following problem: > >states = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14} > >stim = {33, 44, 55, 66, 77} > > >The locations of state 3,5,7,9,11 to be equal 33,44,55,66,77 > >MapThread[{#1 = #2} &, {Take [states, {3, 12, 2}], stim}] > >I tried to the above but it gives me errors: >Set::setraw: Cannot assign to raw object 3 > >However these work individually: >MapThread[#1 &, {Take [states, {3, 12, 2}], stim}] >MapThread[ #2 &, {Take [states, {3, 12, 2}], stim}] > >Any ideas? > >Thanks in advance
