 Author Comment/Response Hyun 08/23/07 3:15pm I have a question about AppendTo. For example, I have 4 outputs. Out[1]= {8, 1} Out[2]= {3, 4} Out[3]= {5, 2} Out[4]= {7, 0} I want to make this data by row. {{8, 1},{3, 4},{5, 2},{7, 0}} I did this step by step by using AppendTo X1results = {} AppendTo[X1results, Out[1]] {{8, 1}} AppendTo[X1results, Out[2]] {{8, 1}, {3, 4}} AppendTo[X1results, Out[3]] {{8, 1}, {3, 4}, {5, 2}} AppendTo[X1results, Out[4]] {{8, 1}, {3, 4}, {5, 2}, {7, 0}} I want to do it at one time by using Do command. But I couldn't do it. Do[ n++ n = n + 1; X1results = {} AppendTo[X1results, Out[n]] , {n, 1, 3} ] Set::write: Tag Times in 1 2 is Protected. >> Thread::tdlen: Objects of unequal length in {} {{7,0},{3,4}} cannot \ be combined. >> Set::write: Tag Times in 2 3 is Protected. >> Thread::tdlen: Objects of unequal length in {} {{7,0},{3,4}} {5,2} \ cannot be combined. >> Thread::tdlen: Objects of unequal length in {} {} {5,2} {{7,0},{3,4}} \ cannot be combined. >> General::stop: Further output of Thread::tdlen will be suppressed \ during this calculation. >> Set::write: Tag Times in 3 4 is Protected. >> General::stop: Further output of Set::write will be suppressed during \ this calculation. >> Please help me. I want to make {{8, 1}, {3, 4}, {5, 2}, {7, 0}} at one time by using some command. Attachment: Question about.nb, URL: ,
