;Iterate function file
;by Brent Hugh
;Window defaults
xmin=-3
xmax=3
ymin=-3
ymax=3
;Parameter defaults
a=2.718281828
b=2.718281828
c=1.01
d=1.01
;the function
x=sinh(c*y*(2*intran(1)-1)) | a
y=sinh(d*x) | b
;A kaleidoscope. Try a large number of iterations on this one--say 10000.
;The formula 2*intran(1)-1 simply changes the sign of y randomly.
;Try other values for a and b. Anything less than 10 is interesting.
