I was wondering if it was possible to plot a graph and
showing the labels (text) like this parcial code:
trimesh(e,nod(:,1),nod(:,2),0*nod(:,1))
view(2),axis equal,axis off,drawnow

Dear all,
For an array, why hilbert transform first, then select an
row, the result is different from  select an row first, then
hilbert that row?  

I have the following problem with the mwArray. I am getting
the content of a cell array in C++ as follows:
mwArray result;
someMatlabFunc(1, result, mwArray(outputfile),

I'm using MATLAB 7.6.0.324 (R2008a) on Windows XP SP2
32-bit. I have a C2D E8400 CPU and 2GB DDR2-800 RAM.
I need to perform this kind of operations in my program.
Surprisingly MATLAB doesn't return the correct value.

I have three vectors of data X, Y and Z that represent a curve in 3D space
(plotted by 'plot3'). These vectors have only 10 points each and I need more
detailled curve so I wonted to find appropriate interpolation function in
Matlab. It looks like the task is not as easy as I ...

I want MATLAB to upload a specific file based on user
commands. The first part of my code asked what file would
you like to upload. I have previous experience using
the "strcmpi" command to ask for data from the user. The

I am working on a data demodulation program for a fiber
optic vibrometer. I have to acquire data using MATLAB DAT.
The problem is that the signal that I have to acquire
drifts (meaning it changes slowly) even if there is no

I'm trying to merge two sources of data.  I have values for
pH vs. time and also potential vs. time.  I want to merge
these two so I can get pH vs. potential.  The times are not
exactly the same so I tried to write an m-file that would

I’m just trying to send a matrix back to matlab. The
problem I encounter is that the first element gets to be a
very small number and I think it should be 2?
Can someone plz tell me why, this is my code:

Is it possible to get gradients of velocity (u,v) in an
incompressible Navier stokes simulation in comsol?
Thanks a lot,

I am using Matlab to gauge how long an operation takes in
Linux. The executable needs an environment variable to
specify how many processors to use (e.g., NUM_OMP_THREADS).
I set in Matlab:

I've made an image of my array using the image function but
I'd like it flipped zertically. Is there an easy way of
doing this?
Also how would I plot a variable which is say, a vector over

I am setting up my first GUI, and I am using the figure
callback WindowButtonMotionFcn. The majority of the
callback function does not do anything until after a file
has been opened and "setup". I implemented this by setting

Hi, I'm trying to add in some text to a wire in simulink.
I cant figure out how to get a dot over the letter, as in
\cod{\phi}
It does not put a dot over phi.

I need to estimate parameters of a defined structure of a
transfer function. Suppose for example the transfer
function K/(s+a).
