Matlab 2009B UIControl callback failure
Unfortunately, I can't provide the source to show this problem off, but here's what's happening: The UI is created programmatically to have various uicontrol->edit elements in it. At the end of spawning all these elements, I use uiwait to wait until the "OK" button (uicontrol push button style) is pressed. The edi... 26 Apr 2010 12:36

symbolic arrays
Is it possible to define symbolic variables of arrays? I want to do syms a(1) a(2) a(3)... so that I can compute the jacobian of a vector valued function. ... 3 May 2010 22:02

the distance between two time series
I'd like a measure that passed some simple tests. Here are a few. The distance should be zero if any of the following are true: 1) Yi = Xi + a 2) Yi = a*Xi 3) ?? -- I don't know what other conditions should be added. And the distance should be one if the following are true: 1) ?? 2) ?? Any ideas? ... 26 Apr 2010 13:46

fft on matlab
Hi. In the example on how to use fft, once they have the signal, they do this: NFFT = 2^nextpow2(L); % Next power of 2 from length of y Y = fft(y,NFFT)/L; Meaning that they get the next power of 2 from length of y (the signal), and then they calculate the NFFT-points fft, to then divide it by L (length of y).... 28 Apr 2010 07:13

Interaction of MEX and MATLAB or mexCallMATLAB and Co.
I am currently implementing some image processing operation that needs to be framed by two nested for-loops running over all columns and rows of the image. Due to the slowness of nested for-loops in MATLAB I decided to code this problem using the MEX interface. I do know how to set up a mexFunction and how to pass i... 28 Apr 2010 05:02

Fourier Transform (fft)

data aquisition delay
Hi there, I have a problem with a data aquisition process. Via the soundcard and speakers I generate a signal and record it with a microphone. The code is as follows: ao = analogoutput('winsound'); addchannel(ao,1); set(ao,'SampleRate',fs); ai=analoginput('winsound'); addchannel(ai,1); set(ai,'SampleRate'... 26 Apr 2010 11:22
