I have a matrix(128,16)
for the first 128 rows the first 32 values i want to place
it in a new matrix and then the next 64 zeros i want it
removed and then attach the next 32 values for all the

When we want to solve Ax=b, we simply use x=A\b.
Here, \ means a lots of things. It internally tests several
algorithms to solve the given problem, chooses the best
one, and yields the solution vector x.

Hi, my Macbook Pro had upgraded to Leopard. I found that Matlab can't print

Hi,
I am doing a real-time control project to control a robotic
manipulator. I built the simulink model in matlab. However,
I do not know how to generate code from realtime workshop

% example:
a.txt{1}  ='aaa'; a.txt{2}='aaa'; a.txt{3}='aaa';
a.num1(1) =  3    a.num1(2)=  6;  a.num1(3)=  9;
a.num2(1) = 30;   a.num2(2)= 60;  a.num2(3)= 90;

If Im using the Matlab plot function, and in the figure i
want to label each data point with a string, so that each
data point will have a label beside it in the figure, does
anyone know how can i do that?

I am using a Hamamatsu EM CCD camera, model C9100-13.  I need to acquire

I have one figure that has five subplots. I'd like to
write titles for each subplots AND one title for this
whole figures at the top.
I wrote a code as follows, but the 'BIG TITLE' was not

Hi  - probably an easy one:
How do I nummerically convolve 2 probability distributions
and see the resulting distribution?
i.e.

Hi my girlfreind has this question, unfortuntly I could not
answer her..please any one can answer
I have a signal transfer function vector H=[H1 H2 H3 . . .
Hm]

I have two data: both data have same x-axis data but
different y-values. I'd like to use double y-axis
(plotyy), AND draw lslines for each data.  
[AX, H1, H2]=plotyy(x, y1, x, y2);

I have a gui created using guide. I would like this gui to
launch in the upper left corner of the screen.
I tried using 'movegui', but I can only get it to work after
the gui has become viewable <ie it does not work within the
