FFT codec problem

Rob153
I have a Natural Electromagnetic Detector Project. It requires a Fast Foreur Transform operation.

I found the page in Arduino, followed the instructions, and installed the library. I checked the include

library and it's all there. Next I ran an example sketch and I get the same error each time what ever

sketch I try FFT.h is not in the library. It is I checked, can any one help?

You haven't installed the library correctly or haven't restarted the Arduino IDE.

Libraries must be in the right place with the right structure - ie the same as the other libraries
you have (and the same as the system libraries in the system libraries directory).
