accelerate processing time [message #49274]

Hi all,
I'm a newbie in IDL and in programming. I have the following question:

I have an irregular point cloud (X,Y,Z), and i must calculate the
euclidean distances several times because I need to do some iterations
to get the final results:

radio=mask /2

FOR i=0L,N_ELEMENTS(z)-1 DO BEGIN

distances=sqrt((x-x[i])^2+(y-y[i])^2) ; Euclidean distances
neighbors=WHERE(distances LE radio)

ENDFOR

If I have 2 million floating points, with several iterations, the
computing time will be very tedious.

Can anyone advice me in a solution for this!

Thank you! Best regards,
Marie
