Segmentation violation error in matlab
Hello, my name is Anna. Currently I am working on my IT project where I use matlab. I have a problem when trying to run the ready code on other computer. It is a GUI program created with guide which works fine on my computer, but when I try to run it on other computer it displays ''Segmentation violation detected at.... 20 Apr 2010 15:54

discharge prediction, ar-model
Hi. I'm nearly new to time analysis as well as AR model. I just can get parameters from AR(x,n) and simulate it using FILTER command, at the moment. Actually, I want to predict discharge in some particular basin from 30 years daily monitored data. It would be grateful if anybody give me some tips for detrending and... 20 Apr 2010 15:53

How to observe QAM singals in time-domain in Simulink?
I am trying to build up an OFMD transmitter by using Simulink. The chosen modulation scheme is 64-QAM. I am wondering how to observe the QAM signals in time-domain. My simulink model consists of the following key blocks: Random integer generator, QAM modulator, S/P converter, IFFT block, Cyclic prefix block, buffer ... 26 Apr 2010 06:56

Unsupported Matlab functions when building model in Real-Time Workshop
Hi, I read information from a device on a serial communication. The data is received as ASCII-signs. For example, the number 1.5 is received as three ASCII-signs (49 46 53). In my simulink model, which I build using Real-Time workshop and download to my control platform (dSpace microautobox), I would like to convert... 20 Apr 2010 15:53

Yule-Walker and Levinson-Durbin Algorithm
Hello, Does any body know how to open the m.file containing the Levinson-Durbin algorithm? The point is that if I used the fucntion aryule to estimate ar coefficients I get some estimates that are far away from the theoretical ones (based on my example). I beleive that the problem can be done by the way the autovarian... 20 Apr 2010 15:58

Warning Using QUAD
Hi, I am using QUAD to perform a numerical integration. My function is pretty complex and is giving me a warning: 'Warning: Minimum step size reached; singularity possible.' This is resulting in a significant error for my problem. Is there any way to control the number of integration points or any other way of so... 20 Apr 2010 15:53
