Hello guys,

If I want to create an array of N positions from A to B I can do it
like this :
result=FINDGEN(N)*(B-A)/(N-1)+A

Right now I would like to create the same array but with a logaritmic
"distribution" and for any positive A and B.
For example, for A = 0, B = 1 and N=10 the result should be
ALOG10(1+FINDGEN(10))

This is easy if A and B are powers of 10 but I don't know how to solve
this problem with any other numbers.
Thnak you in advance for your help,

nata
