I am trying to save a figure after each iteration of a for
loop, but the formatting is not preserved.  When I save the
file as a .jpg, the font size is increase from the default
font size to around size 18 and the windows taskbar is not

I'm working with a large (16793600x400) logical sparse
array named hits, and when I try to access multiple rows of
the array at once, I get less elements than when I access
the rows individually.  For example:

Hi,
I would like to update and display a figure as I do
calculations in a loop.  For example:
t = 0:1:100;

I have a problem dealing with the following ODE system:
C * dx(t)/dt = A - B * x(t) - y(t)
where A,B and C are constants. For this system I have data
from measurements giving a noisy, continous signal of x. My

It looks like something has changed on me.
I've been shown that my selectdata code no longer runs, at least in R2007b.
I've not tested it in R2008a, although I will.

Please help me to provide source code of extract
eye,nose,lip from an image

Im with matlab 7, and i havent got the graycomatrix.m or the graycoprops.m of the image processing toolbox.
Dont really know why....does it happens to you too?? Can anyone help me to get those files?
Thanks everyone!

How do I generate a pdf, given its mean, std, skew and kurtosis ?
The function 'gevpdf' (statistical toolbox) does this for a given
mean, std and skew. The function 'gevfit' fits a model of three
parameters (mean, std, skew) to any data. I'm looking for an extension

I don't get the purpose/usage of the 'offset' parameter in
the glmfit function doc. I browsed through the references
(Dobson and McCullagh), but didn't find a similar parameter.
Does anyone know its meaning?

I have a network that I'm simulation in Matlab. Each node in the
network has events arriving at any time. Instead of using a timer
object which does not allow triggers at irregular intervals, I've
created a 'timer' through checking through iterations of an endless

Hi, i'm implementing a draining tank in simulink.  The
original height starts from a memory block and is
decremented each iteration by a constant flow loss (which
is previously fed into an integrator and the inverse of the

I am trying to write a script that will become a function
for calculating the angular error between two lines, where
one line is the reference line.  My script takes three
points that need not be located near the origin and then

I'm working on a script that I will eventually turn into a
function to use for data analysis.  The idea is to take a
triangle and translate it so that the "start" point is at
the origin.  I then want to rotate the triangle so that the

I am trying to solve

I am working on a class project that I am having a hell of a time with.  I posted a link to a .pdf file that is the actual program.  So far, I have created an .m file with the variables defined and it works fine but now I am having problems with the eigen functions and ...
