I have built an executable of a Matlab code we have that has
the top level m-file name of fset_gui.m...  The command used
to build the executable was simply "mcc -m fset_gui"..  The
executable works but there are a list of warnings that

I have a system of four algebraic equations with a total of 30
variables, 4 of them being independent variables.
This has to be solved symbolically, none of the variables have

Hey all,

Before that I used the function import_abf, that I found in the file

Hi everybody again,
I have to understand and run a relatively complex

m-files, distributed on different subdirectories of the

I am trying to change the options by writing the lines of
code that will change the default algorithm solver

I am trying to plot two functions simultaneously using the
following code. The second plot is giving me the following

I plot a bar figure using grouped style. the m-code that does so is:
figure; bar([cov_filt3(1:4)' cov_filt4(1:4)'], 'group');
now I'd like to changed the color of the bars individually. How does it
work?

I observe strange behavior when requesting subscript-style
indices from FIND (running R2007b on Windows).  I observe
the problem when the input to FIND is 3D (when input is a
matrix there's no problem; I haven't checked to see what

Hi, I'm pretty new to matlab and have only used really basic
aspects so far (mostly just graphing).  What I want to do
now is draw some density contours based on how many points
are plotted in an area of a graph.  I've been looking

I have a gui program from which I build a project using
deploy tool. This procedure will encrypt my M-files.
However, I want to enable other users to make changes to

I have a m file that shows a waitbar, during the evaluation
of a long for loop.
As I'm debugging the file, I often have to interrupt the
evaluation using Ctrl-C. When I do this, the waitbar remains
