I have a simple question, more or less related to
the rebin stuff:

Assume the following routine, which shoud calculate the pairwise
distance of two array of 3-dim vectors:

array=indgen(3,21)

a=array[*,0:5]
b=array[*,6:*]

nA=n_elements(a)/3
nB=n_elements(b)/3

distArr2=fltarr(nA,nB)
for i1=0,nT1-1 do begin

distArr2[i1,*]=sqrt(total((b-rebin(a[*,i1],3,nA))^2,1))
endfor

so far so good, the routine does the job, but is there
a possibility to eliminate the for loop completely?

Greetings,
:-) marc
