Get All Elements from Cell Array
Me again^_^ I read this thread - http://www.mathworks.com/matlabcentral/newsreader/view_thread/276255, however, cannot make it work so have to ask. I would like to select all elements of a row in a matrix using simple matlab function. Here is how I would like to have: matrixA = [0 1 2; 3 4 5; 6 7 8] N = 2 ro... 20 Mar 2010 01:44

color segmentation
hi everybody i have a project for my pattern recognition course, and planning on designing a system the recognizes defective bottles on a conveyor belt with a low hue color background (Red). based on: 1) white spots on the blue bottle (means that the bottle is defective) 2) bottle neck 3) bottle base color (... 19 Mar 2010 21:14

MATLAB compiler
For awhile, I have been compiling a fairly large application (GUIs and functions) with success. The file is about 800KB. Recently, I changed a couple of small things in the code and everything runs fine in MATLAB. Then, when I compile, it says compiled with success, but the file is only 48KB and of course doesn't... 29 Mar 2010 08:01

Solving an equation
Hello all, I'm trying to solve a mechanics of materials equation for buckling using matlab, but I do not know how to solve an equation for a specific variable. My equation is : 0.6 = 0.5(sec(sqrt(P/EI)*60) -1) where EI is defined and P is the unkown I'm solving for. Any help will be greatly appreciated. Thanks i... 19 Mar 2010 18:59

Simulink UDP
I have a c program that sends signals via UDP to UDP receive block in a Simulink model. UDP receive in simulink is in blocking mode because in the non blocking mode signal is very noisy. As per requirements, I have to stop c program first. That causes UDP receive in SIMULINK to time out and pops an error "data ... 19 Mar 2010 17:47

How to simulate multipath signal with fractional delays?
Hi guys, I'm working on multipath delay estimation. I use PN sequence in the transmitter. The chip rate of PN sequence is Tc. It is known that with delays that are integer times of Tc can be estimated by auto-correlation directly. But for arrivals separated by less than Tc seconds can not be solved in this way. ... 19 Mar 2010 20:08
