Warnings in matlabpool/parfar
Hi, I have what I hope is a simple question. I am running some code which sometimes produces a MATLAB:nearlysingularmatrix warning. I have disabled this in the usual way (warning('off','MATLAB:nearlysingularmatrix'), which works fine under serial operation. When I run this program in a parfor loop, however, the warni... 22 Mar 2010 16:48

DSK 6713 - Simulink/Code Composer
Hello, I am trying to generate code using simulink in Code Composer with a simple model for DSK6713, with a ADC directly connected to a DAC. I have Matlab 7.9.0 (R2009b), Code Composer 3.3, DSK 3.1. When I try to generate code in Code Composer appears: "untitled.h", line 25: fatal error: could not ope... 22 Mar 2010 16:48

Barrel Distortion
I need to corret for barrel distortion in a number of images, all taken with the same camera at the same distance away from my target. Is a pin hole transform appropriate or will I need to create a polynomial transform? If I need to create a polynomial transfrom, are there any camera/lens calibration data sets availble... 23 Mar 2010 13:37

alternatives to correlation
Hi. What are the alternatives we have to cross-correllation and auto-correllation?? If I want to find degree to similarity between two sampled signals what options do I have besides doing the obvious correlation?? Thanks in advance. ... 22 Mar 2010 20:39

Question about Vector Computations
Okay, I can do this the long way but I was wondering if there is a specific method of using vector math to achieve the same result. I have two vectors. One is a directional vector starting a the origin and pointing straight forward. We can just say it has a length of 150. Now imagine I have a circle around t... 22 Mar 2010 15:29

power values FFT plot
Hi, I don't understand what the fourier transformation does with the magnitude of the data. Does it square the magnitude of the data? So are the power values in a fft plot actually squared values? Thanks for help! Ruben ... 22 Mar 2010 15:29

Fast Fourier Transform
Hi, I performed a fast fourier transform on my Volt data: b=fft(data). Next I scaled the frequency (variable a) axis and I plotted both b and a. Now I am wondering what the fft power values are. Are they in Volts? Thanks for help! Ruben ... 22 Mar 2010 18:02
