Fast Fourier Transform routine in Tools add-in menu

[Guest]

I'm trying to do a problem using the Fast Fourier Transform routine in the
tools add-in menu. I need some clues as to how to arrange the inputs. Is
there a reference book of instructions for this routine?

how to arrange the inputs.

Hi. What kind of problems are you having? The input can be either 1 column
of data, or 1 row of data. The output data is in the same direction as the
input. The size of the data needs to be a power of 2 (2,4 8, 16, 32..etc)
(It's a radix-2 algorithm). The data can be either Real or Complex. If you
have Complex data, you could use the "Complex" function. Example:
=Complex(3,4)
Post back w/ any questions.
