Given: x = {a,b,c,d,d};
Applying Cases[x,d] gives an output of {a,b,c}......
However, Cases[x,Not[d]] gives as output an empty list { }... I
expected {a,b,c}.....
Why didnt I get that?
This issue came up when using Thread on vectors...and in some cases the
Thread resulted in 0 == 0 so it's output in the list was
True....and I
wanted to remove them....
thanks.....jerry blimbaum
