 Author Comment/Response kaizen 08/22/11 9:59pm Dear all, I am just wondering why I did not get the right outputs from the Do-Loop interation. When I run the Do-loop, I got the wrong results as compared to the results I obtained for an individual iteration. For instance: Case 1 with Do-Loop run from m = 1,3,5 and n = 1,3,5: In[1]:= Do[Clear[........];............;Print[def],{m,1,5,2},{n,1,5,2}] Out[2]:= def(1,1) = 4.153374;def(1,3) = -0.512811; def(1,5) = 0.18633; def(3,1) = -0.528550;def(3,3) = 0.127743; def(3,5) = -0.055111; def(5,1) = 0.174747; def(5,3) = -0.055370; def(5,5) = 0.027538; Case 2 with Do-Loop run individually from (1,1), (1,3), (1,5),(3,1), (3,3), (3,5), (5,1), (5,3) and (5,5): In[1]:= Do[Clear[........];............;Print[def],{m,1,1,1},{n,1,1,1}] Out[1]:= def(1,1) = 4.153374 In[2]:= Do[Clear[........];............;Print[def],{m,1,1,1},{n,3,3,1}] Out[2]:= def(1,3) = -0.372935 In[3]:= Do[Clear[........];............;Print[def],{m,1,1,1},{n,5,5,1}] Out[3]:= def(1,5) = 0.116199 In[4]:= Do[Clear[........];............;Print[def],{m,3,3,1},{n,1,1,1}] Out[4]:= def(3,1) = -0.4518628 In[5]:= Do[Clear[........];............;Print[def],{m,3,3,1},{n,3,3,1}] Out[5]:= def(3,3) = 0.09195776 In[6]:= Do[Clear[........];............;Print[def],{m,3,3,1},{n,5,5,1}] Out[6]:= def(3,5) = -0.02938316251 In[7]:= Do[Clear[........];............;Print[def],{m,5,5,1},{n,1,1,1}] Out[7]:= def(5,1) = 0.19833664459 In[8]:= Do[Clear[........];............;Print[def],{m,5,5,1},{n,3,3,1}] Out[8]:= def(5,3) = -0.06710907582 In[9]:= Do[Clear[........];............;Print[def],{m,5,5,1},{n,5,5,1}] Out[9]:= def(5,5) = 0.021204373 The correct results are shown in case2. Could anyone please let me know why case 1 is not the same as case 2. Please let me know how to fix this case1 so that it would match to the results to case 2. Thank you for any feedback. URL: ,
