You're welcome.

Thank you Laurent and Ken. Both great responses.
What I was forgetting was that vector is a function of the index.
This now makes total sense and I feel like a dummy for not getting
it. Thanks for your responses.

That's a good one, on par with the one line low-pass filter:

(defn lo-pass

Start with
(map foo [1 2 3] [4 5 6] [7 8 9])
That calls foo with the first elements of the collections (so, 1 4 7),
then again with the second (2 5 8

Now I just have to understand it...
The first apply is throwing me a little.

Hi All -
I recall seeing a beautiful method for doing the following on this
site, but cannot seem to find it
I would like to transform
(def a [[1 2 3]
[4 5 6]
[7 8 9]])
to
[[1 4 7]
[2 5 8]
[3 6 9]]
Thanks

I would like to create a vector that contains the max values of each
of the second and third values from this vector
in this case it would be: [5.4, 7.9]
The method to do this that i have seen would be to
1. Transpose the vector using (apply
quot;4.2" "6.6"] ["L" "4.9" "7.9"] ["L" "1.1"

I would like to create a vector that contains the max values of each
of the second and third values from this vector
in this case it would be: [5.4, 7.9]
The method to do this that i have seen would be to
1. Transpose the vector using (apply map vector v)
2. Discard the vector of Ms and
12 matches
