Fixed the problem - I was importing a bunch of numbers from a file, and I
wasn't casting them as doubles. Thanks for the help!

It's a string array. What does your file look like and how do you import it?

This indicates that the values are strings, so you can't make an FFT
from them. Convert your array to float or double array first.

In [3]: mixfracarray=array(mixfrac)
In [4]: mixfracarray.dtype
Out[4]: dtype('|S17')

Try mixfracarray.dtype ...Chuck

In [3]: type(mixfrac)
Out[3]:
In [4]: mixfracarray=array(mixfrac)
In [5]: type(mixfracarray)
Out[5]:
(Is that what you were referring to?)

Hi there -
I've imported some data from a file, and it's in a list called mixfrac. I'd
like to take the Fourier transform of the data, but when I try to take the
FFT of the list, I get this error:
---
TypeError
