Hi, I am a programming newbie and I need advice on how to check that a
table or matrix , for all nonzero entries in a given row, has only one
entry of value 1.
i have another query on why the code below does not work, when i call
convert{1,0,0,0} again, the results given are from an earlier question,
e.g. {1,1} is it initialised wrongly?
Clear[a,convert];
convert[a___] = Sum[a[[i]]*2^(Length[a]-i),{i,1,Length[a]}]
regards, thanks,
joshua
