I'm looking for a way to keep a timer running, even WHILE
another process or calculation keeps busy MATLAB.
For example, this
t1 =

I'd like to search for the last indice of each colon of a matrix that is greater then
a specified value. I came with this but I'd like to avoid the loop :
for i=1:10
    find(x(:,i)>=y(i),1,'last')

I have used MBC toolbox to fit RBF model, but as soon as I
have got the model I found that I couldn't export or even
view it. Please anyone, if you know how to view or export
the mathematical model, help me out of this trouble. thanks

I'm using a Mac with 2, 3 GHz quad-core intel xeon processors, running Mac
OS-X. When I run the following short code:

i have a problem in merging 2 fluorescent images(red and
green images).
I have already analyzed those histogram in each layer.
All those significant layer in red image is in Red and for

I have a set of data that looks like a logarithmic curve with some
waviness to it.  I'm trying to find a model that can fit the curve
fairly closely, but I don't exactly know the best model.  The actual
data is sound energy versus frequency.  If it helps any of you, I can

I'm not very familiar with how Matlab handles the math for
this but I'm having a very tiny problem.
I'm having problems multiplying certain numbers by the
power of 10 and getting the expected results. Below are

I use matlab 2008a version and I try to use Neural nets.
They are quiet flefible but I would like to have a cusom
dividing function. I have the proper m code and I can modify
but how can I declare the custom divide function to

Does anyone have an implementation of a
differential-algebraic boundary value problem in Matlab?

Is it possible to do a high-order (say >x^35) fit with
polyfit? My signal is complex enough but the fitting goes
poorly after 25 degree polynomial or so. The mu-option
doesn't seem to help, the fit just 'explodes' with it.

hi experts..
been using matlab for almost 2 yrs now and have been
running simulations and pricers all this while .. with one
problem which i never came down to solving. HOW DO I CLOCK

Hai,
I am trying to send an array of data from one computer to
another through serial communication. At 2nd computer data
is not getting received properly,

For the first example of "crossvalind" function in the
bioinformatics toolbox:
      % Create a 10-fold cross-validation to compute
classification error.

How does one change the default font size in figures
(xlabel, ylabel, etc.) ?
Thanks,
Amit.

I am a new MATLAB user.I need someone to tell me an internet resource, a website or an ebook where i can find some small projects that i can do in order to enhance my understanding of MATLAB,cas i feel that is the best way to master any scientific package.
Thanks
