shift matrix row-wise by a vector of "shift" values
Hi All! This seems pretty simple, but I am having trouble with it. lets say I have a matrix A A= [1 1 2 0 1 1 3 0 1 1 4 0] that I want to shift horizontally, row wise, where the shift values are in a vector X X= [1 2 3] so that when I would do something like circshift(A,X) I wan... 13 Apr 2010 13:56

Evaluation of difference between two data sets with different sample
Dear Little Dog! I need to evaluate the difference between two data sets that measured from the same sources but with different sample rates. One is sampled with 1000 Hz and the other is 696 Hz. To "decimate" is not working, since the ratio of two sample rates is not an integer. What about linear IN... 13 Apr 2010 12:48

Matlab Compiler Java error in Windows 7
Hello, I installed Matlab 2007a on a Windows 7 computer. I had to set Java folder to new Java version. Matlab works fine. But when I try to compile the code to a dll, I get bunch of Java errors (see below). Why? Any ideas? Thank you. Exception in thread "AWT-EventQueue-0" java.lang.NullPointerExceptio... 13 Apr 2010 11:41

variable sampling rate, ai
Hello everybody, I'm performing some experiments characterized by fast phenomena and slow phenomena over a relatively long time, i.e. 30min. I keep then the SampleRate high to be able to catch the fast phenomena, but of course I end up with really big files. Is there a way to set different SampleRate in different... 13 Apr 2010 11:41

make quiver not show 0
Hi I have a little for loop that goes through and sets values from a quiver to 0 if they are less than a threshold but there are dots where i put zeros, how can I make nothing show up there? ie/ there would be arrows where values are large but nothing where values are small. I tried 'MarkerFaceColor', 'none', '... 13 Apr 2010 12:48

Remove small objects from binary image without erode.
"Ironic Prata" <lixodoironic(a)hotmail.com> wrote in message <hg98tv$2m$1(a)fred.mathworks.com>... Is there a function that removes objects binary image based only on their pixel area? I want to maintain lines, so erode or close is out of the question. Planning on using region props and check each area region... 13 Apr 2010 10:33

combine edge detection with pixel tresholding
For digital detection of abnormalities in an image I treshold the picture so only pixels with a certain value or higher remain because the abnormalities are very bright in the image. After this tresholding there are for example 5 areas left but I want to detect only two of these areas because the other 3 areas are not ... 13 Apr 2010 10:33
