vectorized RK4 [message #51281]

I'm looking at a problem where we have to calculate
a Runge Kutta solution for a number of particles.

From some reading I did, I thought I could vectorize
the RK4 call over the number of particles.

From the help example, we have the following call,
> RK4(Y, allders, X, H, 'differential',/double)

For a single particle
x = 0.0
y = [4.0,6.0]
allders is a 2 element array
H = 0.5
"differential" is a defined function returns a 2 element array.

So, how does one go about vectorizing this for 1000 particles?
Is that possible?
I cannot just pass in vectors for x and y
(and of course have the appropriate differential function)

Cheers,
bob
