arrays yet again

[Ponthieux, Joseph G. (LARC-E1A)[LITES]]

Howdy,

 

I want to build a 100 index array in ICE that looks like

 

0,0,1,1,0,0,1,1,00,1,1 etc

 

I’m guessing that this is doable, but I’m stumped.

OR….

 

An array that looks like

 

0,1,4,5,8,9,12,13,16,17,20,21,etc

 

would also do…

 

Thanks

For the first case, here's one way:

Build an index array of the size you want, and modulo the result by 4.

Build an array [0,0,1,1].

Use the result of the modulo to select a value from this array.

Where are the values coming from?   You could convert a string to an array (String to Array Node)

Or use a (build array from constant node) and replace the values with whatever method you need (modulo etc...) 

[Daniel Brassard]

The other array is also a modulo, this time devided by 2 to select between two values in an array {1,3} and add to the previous number in the main array like so, starting at zero, previous plus one, previous plus three, previous plus one, previous plus three and so on.

[Matt Lind]

I’m not sure if this is easy in ICE, but in coding you could build that pattern very easily with a truth table and an XOR operator.

arggg,
you need to reverse the array at the end, or make it 102 and remove the first 2 entries if you want them to start with 2 zeros.
sorry.

[Christian Freisleder]

forget about the reversing array, it was correct like in the picture

this would be the 2nd case, but there might be an more elegant way.

I could make this array in my sleep with Perl. But….this is not Perl….

Is that anywhere close to a sweet dream?

[Alok Gandhi]

If you can work out array logics in your dreams then yes, it is indeed a sweet dream !
