Hey friends, i am working on simulation of power system using matlab. for that i have written codes for generation side and line side separately. Now i want to use the result of generation file to line file....so how can i use the result of one file to another.... eg i have gen.m file from that i can get hourly gen data....now i want to compare that data to line.....and line modelling is done in separate file line.m so i want to call result of gen.m file to line.m file..... waiting for ur valuable suggestion thanks ...

Hello, This link is not really related to Matlab. So please bear with me a bit. 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 CPUs and OS's) BTW, can anyone tell me an exact link(s) to download FFTW on Windows? On the download site, it says VC6++ is buggy, in what sense? Thanks a lot. http://groups-beta.google.com/group/sci.math.num-analysis/browse_frm/thread/f1d3fe1f0d3fb3f1/8dca568de59a65db?q=fftw+spasmous&rnum=1#8dca568de59a65db This is a link for how I compiled fftw version 2 on Windows...

Hello All, I'm planning to use FFTW library on the DSP....has anybody used it with code composer studio to generate the coff file for the DSP ??..please share your experiences Thanks bngguy 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 spe...

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? I'm running 2007a on OS X.4 (Tiger) on a Core 2 Duo MacBook w/ 2GB o...

Hi. I did a simple test (1d fft) of some data with fftw and matlab. The results seem to differ. I wonder what am I missing? I need to port my codes from matlab to a custom program. Many thanks for any help. fftw: fftw_complex *in, *out; fftw_plan p; int N = 16; in = (fftw_complex*) fftw_malloc(sizeof(fftw_complex) * N); out = (fftw_complex*) fftw_malloc(sizeof(fftw_complex) * N); in[0][0] = -157; in[1][0] = -157; in[2][0] = -163; in[3][0] = -162; in[4][0] = -153; in[5][0] = -147; in[6][0] = -146; in[7][0] = -148; in[8][0] = -152; in[9][0] = -152; in[10][0] = -153; in[11][0] = -154; in[12][0] = -156; in[13][0] = -161; in[14][0] = -160; in[15][0] = -153; for (int i = 0; i < N; i++) in[i][1] = 0; p = fftw_plan_dft_1d(N, in, out, FFTW_FORWARD, FFTW_ESTIMATE); fftw_execute(p); This is what I got: -2475 -40.6284 8.89949 27.4691 3 -5.52795 -10.8995 -5.31273 -7 -5.31273 -10.8995 -5.52795 3 27.4691 8.89949 -40.6284 compare this to the following I got from fft in matlab -2474.00 -39.63 9.90 28.47 4.00 -4.53 -9.90 -4.31 -6.00 -4.31 -9.90 -4.53 4.00 28.47 9.90 -39.63 On May 18, 7:37=A0am, "Marc2050" <maarcc@n_o_s_p_a_m.gmail.com> wrote: > Hi. > > I did a simple test (1d fft) of some data with fftw and matlab. > The results seem to differ.

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: program test implicit none include "fftw3.f" integer N parameter(N=8192) integer pi parameter(pi=3.14159265357) double complex in double complex out double precision f dimension out(N) dimension in(N) dimension f(N) integer i real*8 :: x,y,xmax,xmin,dx integer*8 plan OPEN(UNIT=7,FILE='fftin') OPEN(UNIT=8,FILE='fftout') ! write(*,*) 'Input array:' xmax=1000. xmin=0. dx=(xmax-xmin)/N write(6,* 'XMAX',xmax,'xmin',xmin,'dx',dx,'N',N,'omega',1.0/(2.0*dx)*2*pi do i = 1,N/2+1 x=xmin+dx*(i-1) in(i)=exp(-x)*(-1)**(i+1) if(i.gt.N/2+1) in(i)=0.0 enddo do i=1,N x=xmin+dx*(i-1) write(7,*) i,x,real(in(i)), imag(in(i)) enddo close(7) !call dfftw_plan_r2r_1d (plan, N, in, out, fftw_r2hc, FFTW_ESTIMATE) !call dfftw_plan_dft_r2c_1d(plan,N,in,out,FFTW_ESTIMATE) call dfftw_plan_dft_1d (plan, N, in, out, FFTW_FORWARD, FFTW_ESTIMATE) call dfftw_execute(plan) !write(*,*) 'Output array:' do i = 1,N f(i)=(-N/2+i-1)/(N*dx) write(8,* i,f(i)*2*pi,real(out(i))*dx,imag(out(i))*dx,1./(1.+(f(i)*2.*pi)**2),-f(i)*2.*p...

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.

Hello! 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 fftw('planner','exhaustive') 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, fftw('planner','estimate'). Has anybody else got this stuff to show any improvement? I have played with the fftw3-codebase directly and the speedup using the exhaustive planner in singl...

Hi, 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?

Hi everybody, Here is the situation. I have matlab and a java process that i want to communicate. By the occurrence of an event, this process will send matlab a message containing: - information to be updated in a specific point of a file and; - a command to perform some calculations with the updated data; After this, matlab has to send a message back to the process and inform the result of the calculations that were just done. Can anyone help me with this? Thanks in advance. ...

I also checked my javac -version and java version environment variables by typing each into my command prompt. Honestly I just want to package my code.

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.
