While reformatting some code, I discovered that Matlab
refuses to allow a counter variable to be part of a
structure.  I know this isn't something people should really
have any reason to do, but I couldn't find anything in the

Hi, I'm new to creating GUIs;  I wanted to know if it was
possible to create a pause button for my simulink  
simulation on a GUI.  How would I implement this code in my
GUI?  Thanks for all your help!

I'm trying to re-compile some legacy code on a new Mac Pro
running 10.5 (I don't think this is relevant).
Unfortunately, I can't even compile yprime.c.  Any thoughts?

Hi. I have a GUI that contains a plot, which I'm trying to
be able to save as a PDF at the click of a button. It isn't
working perfectly, however. A PDF is created with the
correct plot and all, but the position/size of the plot in

So I have a matrix A.
Elsewhere in my code I generate a vector x and vector y, for
example
x = [1 4 2]

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
out the figure I created. I got this error message:

Hi I am trying to create a m by P integer matrix
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const
mxArray *prhs[] )

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
images at a rate of at least 100 per second.  Is it possible to do this using the
image acquisition toolbox?

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.
