for loop pair-wise(?)
Hi there, I need to use each pair of 3 columns of a variable, 1-2, 1-3, 2-3 (fancy it's called combination) as inputs in a two-input function. Any idea how to get that into a for loop, if that is a good idea at all? If something like this was already discussed out there, I must have missed the right keywords. Thanks... 17 Jun 2010 07:51

How to plot in MATLAB this simple figure
Hi all I was lookint at this figure which was done in matlab http://mirlab.org/jang/books/audioSignalProcessing/example/dp/output/dtw1Plot01.png I'm trying to understand how to position the plot in the left and the plot just under the square matrix in that particular position. I'm not sure it is something ... 18 Jun 2010 06:57

Result of power is undefined
When using the sim command in 2010a to run a model, I get the warning: Result of power is undefined in ModelName/BlockPath/BlockName What causes this? The exact same code did not do this yesterday. ... 16 Jun 2010 21:02

Image Sequence labelling problem
Hi, I have the following problem, I have a sequence of images of moving cells, some of the cells try to merge and split in subsequent frames. In order to track their movement I tried to label the cells in each of the frames and tried to track their centroid positions. Now the problem is my labelling for each ... 16 Jun 2010 18:49

Problem in calculating area!
Hello, I have some samples that has different degrees of damage. http://drop.io/rlv072i you can see that there are two boundaries. I am trying to calculate the area of the small one. I tried to adjust the contrast, and then use some of the previously posted scripts such as creaseg and ImROI, it couldn't detect... 18 Jun 2010 16:51

shift x coordinate for all x automatic?
Hi guys, I want to shift each x coordinate by +(sqrt(2)*R+2*L)*d, each y coordinate, +(sqrt(2)*R+2*L)*g to each term, and each z coordinate, +(sqrt(2)*R+2*L)*h to each term, without loosing my original image. That way, I have multiple copies of the same structure on one grid. I've tried looking for loops for a... 16 Jun 2010 18:48

MATLAB - Numerical integration
hello, I have a problem with the use of quad function in Matlab for numerical integration. Let me try to explain on an example. When I want to find the integral of expression exp(-x^2/2) from 0 to infinity, where for the higher limit I use some very large number: Q = quad('exp(-x.^2./2)',0,10000000000) I get t... 17 Jun 2010 13:24
