From: Christopher on 31 Mar 2010 14:27 Hi! I tried to use "fftgui" as described in the Section "Fourier Transforms" ->"Visualizing the DFT" in the Help Browser. But when i try to do the examples, Matlab says the following: EDU>> x = [ones(1,25),-ones(1,25)]; EDU>> fftgui(x) ??? Undefined function or method 'fftgui' for input arguments of type 'double'. Any ideas?
From: Lucas GarcĂa on 31 Mar 2010 17:25 Hi Christopher, Apparently, MATLAB is not able to find 'fftgui'. It could be due to several reasons: the directory where fftgui.m is stored is not in your MATLAB path or you don't have that function. However, you can download fftgui.m from here: http://www.mathworks.com/matlabcentral/fileexchange/4822-using-numerical-computing-with-matlab-in-the-classroom Hope it helps.

Are you referring to this page from the documentation? http://www.mathworks.com/access/helpdesk/help/techdoc/math/brenr5t-1.html#brenxms-1 If so, read the Note in the blue box carefully -- it tells you exactly what you need to do to use FFTGUI. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ

Thats perhaps because i use the mac version of Matlab.. But the advice from Lucas solved my problem! Thanks! |
