Kinda new to this, so please bear with me. I'm trying to set up in Excel and use the FFT subroutine included in the download on this site. I copied in the fft.bas and ap.bas (for the complex datatype) into a module, but I can't test because of another datatype that's not defined anywhere; FTPlan (called in the FFTR1DInternalEven subroutine). Is what I'm trying even possible? Please help. Also, the search function for this forum forbids my searching for "Excel," and "FTPlan" was found in one thread that doesn't discuss my issue. Thanks.

The Eng-tips thread here:

http://www.eng-tips.com/viewthread.cfm?qid=279742

has an Excel spreadsheet using the Alglib VBA fft routines. Look down the bottom of the thread for the latest version.

Have a look and if you still have problems let us know.
