Dear experts,
I have slow IDL rouine which contains following for..endfor loops. I
am trying to tranform these loops to array manipulation to improve
speed. However, it is hard for me to solve these.

pind=[0,1,2,3]

for i=0,2 do a_new[*,pind,i] = replicate(1.0,ndata) # aa[pind*3+i]

for i=ngauprm, nprm-1 do pder[*,i] = x[*]^float(i-ngauprm)

Thanks.
