I loaded and used dll with Matlab2007b. All worked fine.
After I tryed the same script in Matlab2008a, it get
crashed. With following message:

Hi this is a stupid question, but is there a short method to
convert a vector into a cell like xd={'0','0.5','1'}. I know
the code below works but its awful. There must be some
simple sprintf command to do it in one line? In the

I'm trying to include the external ACML maths library in a
MEX file that I'm compiling.
The libraries are in /usr/local/acml/gnu64/lib/ and I have run:
export LD_LIBRARY_PATH=/usr/local/acml/gnu64/lib

Just a quick and easy question. Is there a function in matlab that
returns me how many ones are in the binary representation of a decimal
number (which is the hammingweight)? Or do I need to quickly write my
own routine?

I appreciate any comment or suggestion,
I’m trying to capture real-time video and log it to disk
using the image acquisition toolbox (V3.0). Unfortunately,
runtime error happens after few minutes  because the video

I'm using a PixeLINK firewire camera to acquire images.  The
resolution is set at 1600x1200 and makes my computer freeze.
In the PixeLINK OEM capture software, I can set a hardware
decimate that reduces the pixels acquired by 2 (skips every

Hi, I have been running experiments using Matlab and inside
my experiment I use the randsample function to, hopefully,
randomize the order of stimuli in the experiment. I noticed
that some orders came up repeatedly. After using the

  I have some questions in mind using IFFT or FFT from
matlab.
For example, I have 1600 points of data (not symmetrical
waveform).

I need to do a 3D plot but having trouble with the meshgrid function.
The data structure is quite simple, I import a 100 row by 50 column matrix. Each value in this matrix is a respective amplitude value.
So imagine a 3-axis plane, the x axis would have 50 values, y axis would have ...

I'm trying to receive real-time data from both serial and
UDP connection simultaneously for about 7 minutes. Even
though the 3GB switch is already turned on, the virtual
memory is properly set and the data is pre-allocated, I

I am using SimMechanics.  I have the system set up so that
when my simulation finishes, an animation is saved as an
AVI file.  However, when I run the simulation with
Simulink’s Rapid Accelerator, the feature to save the

pls, i need your assistance on this topic. i have a signal
and need to apply low pass filter to it. how do i do that?
The signal is actually a power spectrum in homomorphic
signal processing which requires a rectangular window filter.

Is there  any codes or toolbox that could perform
numerical integration and differentation accuartely on 2D
planar geometries. (Not necessarily rectangular, I have a
circular hole in cyclinder)
