Hi Katty, Could you check your 'Multiplier Impl.' in the 'Implementation' tab in the FFT's parameter box? It appears to me you set it to some vector of length 4, maybe something like [1 1 1 1]? Since your FFT has size 2^6, so you would want to put in a vector of length 6 or just one value (e.g. just 1, as you had before as shown in your previous attached screencap fft3.png)
Hope this helps, Hong On Fri, Dec 21, 2012 at 8:15 AM, katherine viviana cortes urbina < [email protected]> wrote: > Hong, > > I do a fresh git clone of current > casper-astro/mlib_devel<https://github.com/casper-astro/mlib_devel>and delete > the older version since set path of Matlab, but when I prove > the design "Spectrometer" I have a error ; > > > Error using ==> gen_xps_files at 199 > Error due to multiple causes. > > you should see the attachments > > > Cheers > > katty > 2012/12/20 Hong Chen <[email protected]> > >> Hi Katty, >> >> I tried out your parameter setting with the current >> casper-atsro/mlib_devel, and it appears the block is working for me.
