Assume that I have 10 random points on 2D graph, and each point is connected with a spring. So every points is converging to the center of the force for every iterations.
What I am trying to make is a loop that adds a random vector to an existing vector set after each iteration.
So it starts from
v=: <(? 10 2 $ 20) NB. 10 random vectors
n=: <(? 1 2 $ 20) NB. new random vector
force v NB. force function moves the vectors toward to the center
add n NB. add n into v, then #v = 11
force v
add n
force v
add n
...
I'm still working on the force function which seems like to be not hard, but I got really stuck on the add section. Can anyone help me on this? My final goal is to make a loop repeating add force section like 100 times
Thank you!
I agree with Eelvex that the boxes seem redundant. Perhaps the following is a useful way to think about what you are trying to accomplish?
new=: 2 ?@$ 20"_ NB. generates random, length 2 vector
add=: ] , new NB. appends new to right argument
add^:(3) Init=: 4 2 ?@$ 20
11 9
9 16
9 13
0 17
3 3
7 17
6 6
If you have a verb force you could apply that at each iteration too:
force=: -: NB. example verb (halves right argument)
force@add^:(5) Init=: 4 2 ?@$ 20 NB. 5 iterations
