Re: [Discuss-gnuradio] how to use FFT without grc block

[Aditya Dhananjay]

Hi Nasi,

And the problem is in that input part. It is not clear what is inbuf...
I create gr_complex vector and want to input it into fft. It does not work in any way.  There are alot of questions are still open.

You can look at fft.cc and fft_vcc_fftw.cc. It is quite clear how the FFTW library is called by GNU Radio. The documentation of FFTW is also quite good. You can look up how to use a "plan" to calculate forward/reverse FFTs.

Coder is a good coder if his code is readable first. Anyone one can design a confusing language.

With all due respect, Nasi, please refrain from biting the hand that feeds, and then asking for more.

Happy hacking!

best,

aditya
