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.
Sincerely,
Fujio Takata
