Sounds similar to jit.slide or jit.scanslide depending on whether 
you're filtering in time or in space, respectively. Use a slide factor 
of 2 to get the above formula from: y(n) = y(n-1) + ((x(n) - 
y(n-1))/slide)

But otherwise, if these or other objects aren't suitable for your 
purposes, as Gregory mentioned, Java would work well (but don't use 
setcell/getcell. grab and set as an entire array, as the Jitter java 
examples illustrate).
