I have created a gui that has 2 sliders; one slider is the
Target slider, which displays the value that the user needs
to match, and the second slider is the Input slider, which
the user needs to match to the Target slider's displayed

I have created a GUI that takes as a single argument a data
structure. When the gui is launched, it populates values in
the GUI with current values of the struct. The user then
edits the values, and closes the window. I then wish to

Hello group,
because my simulink model is very big and with a lot of subsystems I
want to use a "color schema", giving a all output ports the same
color, all input ports the same color and so on.

I am working on generation of metalab based code for
control response analysis of conventional helicopter. Due
to the non linearity in the model, I am struck in solving
the data smoothening  task.

I was wondering if there was a way to set the directory
using a Matlab command. The reason for this is that I made a
GUI using guide that inputs images and was trying to set the
directory for it to find the images.

Can any of you help me in identifying the correlation of an image?
Basically what I want to find out is, if I have an image, I want to
know whether parts of this image have correlation with another part or
whether they are independent from each other.

Hi Everyone,
I have a movie of less than a minute.
I saved it via "windows movie maker" as .avi file, & then
compressed it to 10/8 mega via "VirtualDub" using "XVID".

my Simulink-Model creates with the "To File"-Block a mat-
file.
When I let run the model again, this will overwrite the
mat-file.

Can anyone explain/motivate the design decision to switch
columns and rows for displaying images in MatLab?  It just
seems like an extra headache to me, so I'm curious what
this could be handy for.  Is this behavior standard in

I want to capture images from a firewire camera in Matlab.
I don't have the Image Acq. Toolbox. I don't know where to

Dear Someone

I'm just getting started with Matlab so I've got quite a
few questions, mostly regarding command line operation at
this point.  I realize there is a Matlab compiler but for
now I need to run the applications directly from their .m
