I encountered a very strang problem and I hope you can help me.
I developed an application with MATLAB 2007B, and one part of this
application is to plot a figure, and its structure is as the
following:

I'm using MATLAB with the CMU driver for my Firewire AVT
Guppy Camera.
When I use the hardware trigger of the camera, I get a
warning when I use the getdata command.

I am writing a simulink program using S-function. In that
program, I am reading vector from mat file that I need to
compare against real time data at every sample time. And,
also I want to do some calculation between real time data

I'm looking for a way to display a simple progress monitor
by outputting text to the command window.
Currently the only way I've found of doing this is like so:

the curve is very random ( so cannot be interpolated by the

I have a function that returns a vector v1, I can do the following:
size(v1)
ans =

I have: a vector of latitude (call it lat is 31x1), a vector
of longitude (1x58), and my data (call it data 31x58). It is
in spherical grid. I need to translate my coordinate system
into cartesian grid. This requires translating coordinates

Hi I have written some rather length code for optimisation
using genetic algorithms but it is very slow at running
which is limiting its use. I have made attempts to
vectorise it, but hit brick walls with regards to some of

The code that I wrote for fmincon works for some starting
points, but not for the others. Why could this happen? Is
this a problem with fmincon?

Hi,everyone,
I tried to find out the mathematic relationship expression

Hi guys, I need a help!!
I need to link a .m file to a list of persons.
