pixelwise regression for time series images [message #70898]

I’ve written a program that uses LINFIT to calculate a linear model to
each pixel in a multitemporal, registered series of images. That is,
I fit a line in the time (z-) dimension at each x,y pixel location.
However, I am using nested loops to do this and it takes a while to
run. For larger images (1024X1024) there is no hope. I am wondering
if you’ve come across a better (IDL-esque) method of doing this; I’ve
not seen anything online.

Thanks for any suggestions,

brad
