Hi experts,
I use a m-file to build a figure with data from simulations
in Simulink. Depending on the screen width, my figure can
only show about 1500 pixel (i.e. there are only 1500 values

I am trying to estimate missing data from facial images. To do this i am
taking advantage of the known covariance of the pattern class. Using the
Lagrange multiplier technique i am forming the unknown Matrix:
B=UP' * inv([PUP'])

When I try to compile my model (using CTRL-B), I get the
following error:
Error building Real-Time Workshop target for block diagram

ich habe eine Text-Datei, die Zahlen mit Komma enthält.
Wenn ich diese Datei mit Load-Befehl öffne, Matlab betrachtet jede Zahl zwei
Zahlen eine vor u. die Zweite nach dem Komma.
meine Frage wie kann ich diese Datei richtig öffnen

I am using the round.m function to calculate a simple
floating number. However, I cannot figure out why the
following two ways of calcaulating the same thing give me
different answer. Can anyone help?

I have been using the Optimization Toolbox with Matlab 2007.
I just installed 2008a and it seems that nothing from the
toolbox works any more!
An example straight from the help of fminunc:

Is this function limited to axes and uicontrol objects?  I
have annotation objects that I would like to programatically
be able to select, move, and resize.  However, when I set
the ButtonDownFcn callback to 'selectmoveresize', it behaves

anybody can teach me how to program root of nodes by using
matlab
i mean how to link all graph of nodes

I have two graphs:
figure (1)
subplot(2, 1, 1)
x=[1, 3, 5, 7, 9];

how can i merge two graphs from of two simulations onto
common axes?
for one value of a parameter i get one graph on the scope
and for another value i get another graph both of the same

I am new ti Matlab can any one show the code of breaking an Image
into smaller ones say to break an 512 * 512  image into 8*8 smaller
parts on which we need to apply some function.

I would like to update the current Matlab version from 7.4 to 7.6 and to
be able to do that I would need to get hold of the actitivation key. I
have the license number which is easy to obtain by just typing "ver".
However, I have no idea how access the activation key, could ...

I have a binary file and I am trying to read it into a matrix
I used the following commands:
fid=fopen(filename, 'r');
A=fread(fid, filename, 'float');

I have to create an other file the same usborder.mat for my
country.
How can I create and How can I edit file usborder.mat
Thanks for your reading :)

I like to write the equivalent of Matlab's A./B in math. Is there an
expression/notation that can do that?
