Help from Matlab users in UK?
I am PhD student in Health Sciences exploring the application of
Matlab (Statistical Toolbox) for cluster analysis with a set of data.
I need some basic help to get started and would be willing to pay
someone for several sessions. I would be glad to hear from users
based in or near London.
MATLAB is a very simple programming language, get any basic MATLAB
book and you will be up and running in no time.

I'm trying to implement an image segmentation process, and the paper
I'm working from says:
"Finally the smallest 4-sided polygon surrounding the segmented code [
a convex polygon ] is evaluated. This is a special case of convex hull
evaluation, in which the hull is constrained to have exactly four
sides. The output consists in a list of four points which are the
vertices of a general polygon surrounding the code".
And I can't find an algorithm for that, perhaps because I'm using all
the wrong words.
I believe I'm looking for the minimal enclosing...Displaying a data number on the graph
Ok, I am re-posting as it seems I was not clear.
I'm successfully plotting column 14 of a 15 columns data file made of
one single block. Here is the command line:
plot "TS-plus.csv" using 1:14:xticlabel(2) title "VARIANCE" with lines
linecolor rgb "blue"
Now I need ALSO to display on the same graph the last number of col
14, i.e. the number on top of column 14 of the data file, which is
0.5667. I need displaying only that and no other numbers.
I can display all the numbers in col 14 using this command line:

I am trying to convert a Mathcad file and I don't know what to use as a Matlab equivalent for some of the functions.
Comp(T,niH2,niH2O,niCO,niCO2,niCH4,niN2) := Find(a,b,c2,d,e2)
It appears to rely on the rules given above to find solve the following equations.
2a + 2b + 4e2 = 2niH2 + 2niH2O + 4niCH4
c2 + d + e2 = niCO + niCO2 + niCH4
b + c2 + 2d = niH2O + niCO + 2niCO2
Kp1(T) = ad/bc2
I am a little stumped by it right now.
Also there is another mathcad function that I hope to confirm

I am working on an application that takes periodic snapshots of the screen,
which are saved when the application ends. These bitmaps are then used as a
record of the user's activity and can be 'replayed' as a very simple -- and
jerky (which is fine) -- movie (ok, more like a slide show... still fine).
The main drawback of this approach is the waste of memory and disk space,
since most images compare with there predecessors in most respects (for

I'm running an intense simulation which applies an IIR Filter on a large amount of data.
I'm using Matlab's filter function - http://www.mathworks.com/help/techdoc/ref/filter.html

I was wondering if anyone has experience how to speed it up?
Any MEX file?
