I'm testing my ability to implement "fmincon" on a simple Maximum
Likelihood Problem:  estimate the mean/std parameters  (mu,sigma)  of
a Gaussian distribution by minimizing the negative log-likelihood
function.  Let's pretend that the mean (mu) must be a positive number

I created a pop up menu with guide and and entered the text
"select frequency" into it.
I also have an open file dialog box.
I want to uptate pop up menu content after the files opened

I am making a movie of several figures in my windows
machine. I got the code from the newsgroup or the help, I
can't remember exactly.  
In any case the code makes a .avi file but of course once I

 I have two NxN matrices with each column contains N random but
unique intergers which is randomly picked from a series [1:2*N]. Now,
I want to find out how many number in the corresponding column are the
same. For example, consider

I was wondering if anyone wrote or met a function that was
inverting regexp.
For instance, let's suppose I want to extract tokens out a a
string. I can do that with regexp:

The code (below) should be simple, but I can't get it to
work. Could you guide me please.
for (mz = 1:2078)
   if (spectclusters(mz,2:64) == 0)

Hi to all,
I have a question. Suppose I have data from a study that
lasts 6 years. Some people are being censored within the
study, and others who haven't suffered the event until the

I get error message when I'm trying to use IF expresion in
"Embedded Matlab Fcn Block". Input to the block are 4
matrices [3x3]. Next "i_A" and "i_F" are used as parameters,
which are defineg in "Model Properties/InitFcn".

I'm using "griddatan" to interpolate 4-dimensional
scattered matrix.  
However, "griddatan" seems very slow in a trajectory
simulation  which calls "griddatan" hundred-thousand times

Given an equation of the form:
A = b(1+b) + g(1+g)
where; A, b and g are restricted to integers
A is known, b and g are unknown

Am new to Matlab, but need to learn fast. Am working with a
very large csv file that contains data as output from a mass
spectrometer, with m/z values in the first column, and all
intensity values in the following columns. Now, I want to

I am having trouble with my code in the following IF
statement situation:
___________________________
for i=1:2

I know this must be easy, but I just don't seem to find it:
How can I tell plot to plot the line between data points not as a
function (sort the x-values), but to plot them in order of appearance in
my vector? Or do I need an other command?

I am having trouble with my code in the following IF
statement situation:
___________________________
for i=1:2

I'm trying to display consecutive plots, so that they appear
animated. For instance:
for i = 1:100
   plot([0 100],[0 100],'k',i,i,'o')
