Thanks for your answer Marteen. But these solutions didn't work, I
think I missed to say that my 'x' number is a float array with size of
1461.

When I tried this one, it gives both a and b zero.

When I tried to use this one, I changed my float array 'x' into string
array, and here is the error I got:

IDL> parts=strsplit(nu,".",/extract)
% Compiled module: STRSPLIT.
% STRTOK: Expression must be a scalar or 1 element array in this
context: STRINGIN.
% Error occurred at: STRSPLIT 32 /usr/local/rsi/idl_6.3/lib/
strsplit.pro
% $MAIN$

Is there any other way for arrays?
Thanks in advance,
Nusret
