G'day Mathgroup,
Quick question,
I have three lists
x={1,2,3}
y={5,6,7}
z={8,9,10}.
How do I go about operating on the lists in parallel to give me a
cumulative value of f.
As an example, for the general function defined by
f=x*a0 + y*b0 + z*b0,
with initial conditions
a0=0; b0=0; c0=1;
x=1; y=5; z=8;
so
f(1) = z
f(2) = f(1) + 2*f(1) + 6*f(1) + 9*f(1)
f(3) = f(1) + f(2) + 3*(f2) + 7*(f2) + 10*f(2).
I understand that the above can be done by FoldList, but how do I slot in
different numbers from three different lists at the same time.
Thanks
Yas
