list equal list if statement
« on: September 02, 2010, 09:41:11 pm »
Is it possible to have "If L1=L2"?
Specifically, I'm trying to add two lists together and see if they equal a third.  I realize this is possible through a For( loop, but it seems too simple not to have a command that does this.

Thanks, I thought it would be that simple.  I should really make sure I know all the list commands.

Ok, lets say L1 = {1,2,0,4} and L2 = {1,2,3,0}
L1 = L2 == {1,1,0,0}
min({1,1,0,0}) = 0

Now if L1 = {1,2,3,4} and L2 = {1,2,3,4}
L1 = L2 == {1,1,1,1}
min({1,1,1,1}) = 1

Oh, ok. So basically you're just testing to see if there is a zero in any of the boolean between the lists?

Yep, which would mean that one of the elements is not the same :)

WOW, thanks so much for this! I never thought about doing that. I remember back in 2002 or 2003 I wondered how to do that, and never figured out. Nice trick you got there!

Yep, and there are still some crazy optimizations that I can never get no matter how long I stare at them :D

Yeah same here. if you read one of the Illusiat 13 topics, Galandros explained it thoroughly and then I checked the TIBD page a few times. I never managed to understand how it works. so I stuck with a slower alternative x.x
