I am looking to create a smooth 3d image from a set of XYZ
coordinate points. For instance, i have about 100,000 points
that form the shape of a cone, and i would like to try and
recreate a 3d image of it that has actual sides and is not

I've built a GUI and created a standalone executable for it
but it needs matlab installed to run.  
If I install mcrinstaller on a PC without matlab the GUI
runs fine but is there a licensing issue doing this?

I have a series of functions that will be deployed on a number of
different machines which may be running  Windows, Linux or MacOS.  I
need to run a couple of system calls, which will have to change based
on the OS.

Hi ppl.
I want to use an IF function, in which it verifies if a
number is integer and if it's also a multiple of 16.
How do I do that?

How can I use "findall" and/or "findobj" to count the number of figures that are
open (even if they are invisible) ?
Thanks.

My GUI has 4 subplots in it, defined using
axes(handles.plotname), and a few buttons. On a save
pushbutton i would like to save the full GUI figure.
The handlevisibility is set on callback, the integerhandle

I'm trying to implement a Kalman filter in MATLAB that will use two
types of measurements: volume and in/out flow rate. For the flow rate,
the measurement error is additive Gaussian, but for the volume the
measurement error is expressed as a percentage of the volume, so that

Lets see... I have a mass/spring/damper model in simulink, I
then used RTW to build a standalone executable. I used GUIDE
to build a GUI app that will let the user enter values for
simulation time, mass, spring constant, damping constant.

Hi everyone, I am trying to store in a loop the results from fmincon.
The function has two variables so I would like to store in the first element the whole optimal decision...
for iw=1:nw            
[t(iw),t(iw)] = fmincon(@(x) obj2(x,W(iw)),[-bmin 0], [1 1; 0 0],[W(iw);0],[],[] ...

I am working with model reduction algorithms. I have 1 bode
plot of the original system, then a bode plot of a reduced
order system.
My problem is that i dont know how to compare the plots, get

I have a question about how MatLab treats vectors and scalars. It
appears there are instances where MatLab will will implicitly treat a
scalar like a vector. Here is a simple example:
x = [1,2];

I'm trying to overload subsref for my class, and in the process I came
across a weird thing. Get doesn't work the way I think ti's supposed
to. I want to do a simple thing, which is to access a property using a
get, not a dot notation. That fails for some reason. Any idea why?

can any body help me????
My pronlem is that:
I want to distribute say 100 transceiver within 100x100
sq.m area using poisson distribution function. After this

It appears that MATLAB Stats toolbox has t location-scale
density.  What is its handle for our using?  Has anyone
tried using this library for their simulation of the
distribution?  Does MATLAB also have an inverse t

I am getting a warning "iteration limit reached" while
using GLMFIT function.
How can I increase this iteration limit? I looked into the
code and figured it has hard coded iteration limit set to
