Doug:
I am kind of in the same boat as you. I have to do a FFT on a data set w/ 2
columns of numbers. I was able to read in the data. I had to make sure it
was a textfile. Then when I did an FFT on the data it seem to process it.
QUESTION: The data I have are paired numbers, time and voltage. Do you
know how to transform a data set in the form {T,V} where V=V(T)???
Perhaps we can help each other.
