Hello J-ers.
Consider this
wave=: 3 : 0
('N';'D';'L';'S')=.y
A=.,(i.N)j./-i.D
k=.(0j_2p1%L)&*
c=.S&*&^&+
(+ c&.k)A
)
'dot; pensize 4' plot wave 65 29 32 _0.5
Maximize the plot window to get the proportions right.
This shows the power of J, arrays, and the complex number exponential function.
Do anyone know how to animate this such that the waves are rolling?
