A = {a, b, c}; B = {d, e, f}; C = Thread[{A, B}] {{a, d}, {b, e}, {c, f}} C = Transpose[{A, B}] {{a, d}, {b, e}, {c, f}} Bob Hanlon Chantilly, VA USA ______________________ Dear member of MathGroup: I would like to report a problem with Mathematica. My trouble is as follows: Consider two rows such as A={a,b,c} and B={d,e,f}. Under the above assumption, I would like to obtain a following row C={{{a,d},{b,e},{c,f}}. I programmed in this way; C={{A[[1]],B[[1]]}, {A[[2]], B[[2]]}, {A[[3]], B[[3]]}}. I obtained a required conclusion, but my programming needs too many steps such as {A[[100]],B[[100]]}. In fact, I suppose that the rows consist of more 500 elements. So, I hope to know easier programming with Mathematica. P.S. My Mathematica is 3.0 version for Macintosh.
