Re: Very simple question

There is a problem with your entry of the argument to fx. If it is
re-entered, the function works partially. It works only partially because
pt2 and pt3 are undefined. Presumably you meant to use pt1 throughout.
Doing that causes fx and fy to return the same results.


fx[pt1_]:=Module[{x1,y1,x2,y2,x3,y3},

Print[pt1];

x1=pt1[[1,1]];y1=pt1[[1,2]];

x2=pt1[[2,1]];y2=pt1[[2,2]];

x3=pt1[[3,1]];y3=pt1[[3,2]];

Print[x1,y1,x2,y2,x3,y3];]


fx[{{1,2},{3,5},{4,7}}]


{{1,2},{3,5},{4,7}}

fy[pt1_]:=Module[{zz,x1,y1,x2,y2,x3,y3},

zz=pt1;

Print[zz];

x1=zz[[1,1]];y1=zz[[1,2]];

x2=zz[[2,1]];y2=zz[[2,2]];

x3=zz[[3,1]];y3=zz[[3,2]];

Print[x1,y1,x2,y2,x3,y3]]


fy[{{1,2},{3,5},{4,7}}]


{{1,2},{3,5},{4,7}}

All of these assignments are unnecessary.


Print@@Flatten@{{1,2},{3,5},{4,7}}
