Dear members: Im my matlab homework, I am required to plot the spectrum of x[n]=(0.8)^|n-10| Using fomular I calculate X(omega)=exp(-j*omega*10)*(1-0.8^n)/(1-2*0.8cos(omega)+0.8^2) Because when I plot X(omega) , Matlab warns me that it neglects some imaginary numbers/, I am wondering if it makes sense to plot X(omega) in matlab or noone does that, they plot abs(X(omega)) and phase of...

okay guys, what do you do, if you start with an alg that works pretty good in MATLAB/Octave/MathCad/Mathematica/whatever, and you wanna make production code out of it. let's pretend the production code will be C. what do you do? rewrite it yourself, line by line? use http://www.mathworks.com/products/matlab-coder/ ? something else? (i guess i would also be interested in hearing...

Hi, I was wondering if for an underdetermined system the Matlab mldivide (equivalent to \) function will retrurn the minimum norm solution, or if the returned solution is constrained in another way or if the solution has no particular properties beyond satisfying the set of equations ? The matlab help page doesn't help me. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/ml...

Hi All, I am performing Integer DCT on Lena image. I am using " C "& i am not able to reconstruct the image correctly. Before applying DCT I am subtracting 128 from all pixels of input image. After IDCT i am adding 128 to the result image. I want to compare my results with MATLAB . Is anybody know how to use dct i.e. dct2 function of MATLAB? if anyone has the related code in MATLAB please...

Hi all I'm running a massive test harness on DSK6416, I'll send the input data from Matlab via RTDX to the target and I get back the data for analyzing in Matlab via RTDX. After a while , matlab reported a failure in input channel , at the same time the CCS has crashed and error in CCS is as following "stack overflow" Comments or suggestions would be very much appreciated. thanks ...

Hello, I want to implement RBF interpolation in Matlab for 2D signal (image) interpolation. What I like to know is: 1- Is there any freely available RBF interpolator source code for Matlab? 2- How can I implement it? I read a lot about its theory but I couldn't figure out how an implementation is working. 3- If there is a C implementation, I maybe able to port it to Matlab ...

Can anyone help me? I can't find enough information about standard Inmarsat-C. I found information about Inmarsat-C in the group FAQ-Inmarsat, but this information isn't correctly. I built Matlab receive model and I use Matlab BPSK demodulator. I tryied with this demodulator, afterthat I changed it with Matlab DBPSK demodulator, but results were mostly same. I didn't see synchroword and struc...

Hello Does anyone have a hint on how to convert a set of 12-bites unsigned interger to float, using matlab? Matlab shows the following syntax using float a = float('single') a = float('double') a = float(TotalBits, ExpBits) // here is an example of 12-bit unsigned int x=[ 2843 2845 2851 2869 2838 2840 2853 2864]; I have tried these 3 float syntaxes , but i don't get any c...

Hi, This is a Matlab specific question. I posted this question on Matlab DSP discussion group, but it never showed up. So, I am asking the question here (I have posted questions on the Matlab group before, but it would always show up). But anyways, here is my question: I have always been unclear about why freqz behaves this way, and to me this doesn?t really make sense. Let me expla

do anyone know how to write nist sphere file using matlab ? i need to write new resample file in NIST format but i cant do it using matlab 7 cuz there is only readwav,writewav,readsph (to read sphere format only). i need new resampled 8Khz file as input for gsm and celp encoder . can matlab run any '.exe' file because my encoder is in encoder.exe file. Im using libsndfile library to en...

Hi, I am currently in the process of expanding upon some matlab functions, that is, to explicitly write out the code for a function. I have been trying to write code to give the results of COV in matlab (I got it for a bit, then mysteriously to me, it stopped working when i relocated code)... Anyway, has anyone gone through this process or come across code that would be of help to me?...

Hi all, I understand the subject of similiarity of signals has dsicuss many of times in this forum however i still need some valuable advice and help. My problem is that i am trying to find the percentage of similiarity of 2 signals using matlab? Say in matlab i have just a variable called signal1 and signal2 both of size [1 by 5000] these signal 1 and signal 2 are EEG signals. I just w...

Hi All, I am working on a simulation in Matlab. Basically I have 12 random spread spectrum signals sampled. Then I have Matlab randomly pick one of these and add AWGN on. Finally, I use matched filtering of this random signal to each of the 12 predefined signals and repeat this several times at various SNRs. The goal is obviously to detect which of the 12 predefined signals is being used he...

Hi I am in need of a MPEG/H.264 codec in matlab. I want to play with the compressed bitstream i.e. headers , motion vectors ,VLCs etc. I need to convert a video into mpeg bitstream .... and then put my watermark in this compressed domain. It would be great if anyone could provide a solution(preferably in matlab) for the above .... Thanks and regards chaitanya

Hi all In the GUI in matlab i am creating a single sin wave with a freq between 1KHz-15Khz in steps 1KHz. In matlab iam using the fft() function to get the freq specturm and then get mag and find the peak which will give me the freq. But i need to make a GUI version of this and cant seem to get any thing to work . can anyone help or give me a website to look at. Thanks James_Bond

Hi, I was trying to reuse my old RAKE receiver matlab code which also includes delay acquisition and channel estimation. It still works fine for AWGN, but it doesn't work at all when I try to use it with a fading channel generated by using the 'rayleighchan' function from Matlab. So I tried a few tests: 1) Instead of using the estimated channel coefficients, I let the RAKE receiver have perfe...

Dear all I not very familiar with filter design in Matlab and I am probably missing something when it comes to "group delay". My problem comes as follows. From what I have understood, if I have a filter such that its group delay response (plotted with grpdelay[b,a] in matlab with a,b the filter coefficients) provides 17 as the group delay (in samples) at f=0.14 (normalized frequency so f=0.1...

Hi, I'm using a Software that allos me to link a Matlab File integrating it for the simulations. The Help Tool of the Software tells that I've to execute some comands before running simulation. the exact intructions are: "The PATH environment variable should include the bin directory under the MATLAB root directory. This example shows how PATH can be set: set PATH= \bin\win32;
