Hi everybody,
I am a newbie in Mathematica and began programming with it. Could
anyone explain this problem to me ?
why mathematica can't deal with
l={{1,2,3},{2,4,5}}
l[[1]][[2]]=3
and here is its error message :
Set::"setps": "\!\(l \[LeftDoubleBracket] 1 \[RightDoubleBracket]\) in
\
assignment of part is not a symbol."
but it can with
Part[l,1,2]=3
