I have an easy questions for you expert of matlab.
I need to dock a matlab figure in another figure.
What is the procedure ???

If I only use a Intel Pentium PC and VC6++ compiler, is it possible
to minimize the footprint of FFTW? (because some files are for other

On the download site, it says VC6++ is buggy, in what sense?

I woould suggest that you use the manufacturer's optimized FFT vice FFTW.
FFTW is designed for general purpose processors. The chip maker will have
special code that takes advantage of all the special hardware designed into
the DSP chip. FFTs execution speed is a major marketing number so all chip
vendors that I am aware put lots of effort into getting the best possible

...one complex fft2 vs. two real fft2's with fftw
I have a function performing the fft2/ifft2 of two arrays, e.g. 'a' and 'b' (doubles, strictly real). From an overly simplistic test script (see below), the profiler shows it to be 35% quicker if I use fft2/ifft2(a+i*b) rather than performing the operations on the arrays individually [1024x1024] (discovered on a lark).
Does anyone have any experience/insight on this? Is this just because I haven't done any tuning with fftw? Would it be worthwhile building an fftw wisdom base for arrays this small?

Hi, I am using FFTW to try another test, f(t)=exp(-x), x>=0, the real par
of the Fourier transforms should be 1/(1+x^2). I use xmax=1000, and xmin=0
let N=8192. I found the results seems shifted upper, every output value i
larger than the analytical solution.
My code is like this:
double complex in
double complex out
double precision f

Too bad for that theory, given that iPod sales are trending down,
iPhone/Touch is trending up, but doesn't match Apple's biggest income
source, which is its Mac lineup.

May be true, but more ads and effort is behind the phone. Or had you
not noticed that the Mac ads are way down?

I'm trying to evaluate the speed of fftw in matlab 7 (R14) but I can't
get it to use the planner.
One of the calls I'm trying to get to work is
It seems that the first call to fft2() takes a lot of time
which makes sense but the time of the time (tic,toc) of subsequent
calls are exactly the same as with the trivial planner,
Has anybody else got this stuff to show any improvement?

I'm starting to learn DSP (Matlab )and I have two questions about it,
maybe someone can help me out?
I'm trying to measure a frequency from an Audio Device and I'm using FFT
to transform it from the time domain to the frequency domain. But I am
doing a downsample before the FFT. But you can also do it after the FFT.
Do you know what would be the most efficient (before or after)? And why?
Another question, I am using zero padding to increase my system resolution
(up to 50Hz). My frame length is N=256 and sample frequency fs= 44100 Hz.
So 44100/50 = 882, so I need to add 626 zeroes (to 256 frame length) to
get 50 Hz resolution, I hope this is correct? I believe this is done for
FFT. But is this the same for the DFT?
Thank you and regards,

Now when I click start in the MATLAB GUI and goto the MATLAB option then over to "MATLAB Builder JA". It shows up so I am assuming it should be working.
I also checked my javac -version and java version environment variables by typing each into my command prompt.

I'm familiar with stationary (FIR/IIR) and adaptive filtering. My matlab
skills are OK but I've never done any practical DSP in matlab. There is a
book called "Digital Signal Processing using Matlab" by Ingle and Proakis.
It starts with very simple things which I find extremely boring so I
wonder whether it's the best way to learn how to process some signals.
Any useful tutorials or advice would be welcome.

"When all you have is a hammer, everything starts to look like a nail."
Matlab can be an amazing tool for mathematics. For signal processing it leaves a
few things to be desired. (I'll leave it to others to be specific about this.)
For LEARNING signal processing, it's like learning to drive in a car with an
automatic transmission -- you'll do okay, but you won't understand the
fundamental relationships between torque, RPM, gearing, etc. And unless you
specifically set out to learn them, you'll be limited to driving cars with
automatic transmissions for your whole life.
