I'm trying to use a set of COM objects in Matlab. I read a
lot of resources (Matworks and others) about it, but can't
get it work. I hope someone is willing to help me!
Some background info: the dlls are supplied with the Tobii

I wish to pull out data from a structure array and put it
into csv files but i was wondering if there was an easy way
to do this:
for i = 1:6

i have a code to separate many objects in an image But
when implement it will appear this message:
??? Undefined function or variable 'bwboundaries'.
Error in ==> E:\d\MATLAB6p5\bin\win32\isolate.m

does the new GUI control 'table' support the mcc command?
i found the .exe file  produced by 'mcc' command cannot run
normally.
i want to know, is this a not found bug in 2008a matlab?

Does somebody know how to increase the com ports available
for the query instrument block?
I have only com1-4 to choose from...

I'm trying to plot 2 datasets on one figure with a separate
Y axis on either side of the figure.
I've tried using plotyy and the help browser's suggestions
with regard to plotting multiple axes but this is giving me

  I used matlab 14.4 to transfer M-file to c code.
The original M-file is            
fid = fopen('tx_para.txt','r')   It works
  But after it transfer to c code, it shows error:

Are the hotkeys user definable?
In my case, I would like to call a function from GUI using
hotkey (or a combination of keystrokes). I want to zoom out
of the current figure by type in Ctrl+whatever. How do I do

Dear Matlab Community,
I am iteratively solving a least squares problem with lagrange
conditions [A'*A B; B' 0]*[x; k]=[c d]. To check for outliers I would
also like to calculate a L1 norm solution, e.g. min(sum( |c|)) instead

Hi, evvryone!
How to compute the following rectangle double integration
problem:
int_{-c}^{c} int_{-c}^{c} f(x,y) dy dx

I probably going to change my loyal laptop. As I do a lot of
MATLAB computing, I'm certainly interested in knowing how
your computer scores in MATLAB bench test (I do bench(10)
and take the median the result). I'm open to all kind of OS

I was trying to build program similar below:
First class:
classdef A < handle
 % a good class with only basic datatype properties

I have data that has something like the following in each line, and
there are about 1000 lines with different values of:
BETA, THETA, PHI, VALUE1, VALUE2, VALUE3
Where BETA, THETA, and PHI are angles.   A 3-D polar plot makes sense,

I have a quick question.  
I have data listed in 10 minute intervals and I was
wondering how to average it, so that the data is now in 30
minute intervals.  The data is already in a .mat file.  I

I am getting an error when I try type in the following
variable expression:
