I write Matlab code for some time. Now I find it is difficult to write
similar thing in simulink. This is an example.
I have a matrix:
Cn =

I am using GA for a certain problem. In this problem, my
variables are integer numbers e.g. between 1 & 99.  My
difficulty is in setting upper bound on the variables.  To
start with I have set the population type to ‘BitString’,

hi, eveyone, I got a problem transfering a txt file to cell array, the

I'm trying to display 1 slice from a 3D array that's
512x512x3 using the slice function.  The 3D array is called
CTdatasetin2.  The values range from 0 - 8 but I only want

I have written a program to track communication between
different nodes. My model has got 9 nodes, one node is
transmitter while 8 other are receivers. The simulation runs
for 300 seconds and calculates loss every 20th second for

I am trying to graph multiple plots on the same graph. I was
wondering how you go about doing that. I tried using the
hold command but keeps on giving me weird results. Also I
wondering how you use factorial in matlab.

I have a set of spectra files in a subdirectory.  I also
have a cell structure containing the ascii file names of
each of a subset of the files.  I want to use file copyfiles
to move the subset to a new subdirectory.

Hello. I am creating and writing to a text file using fopen
followed by fprintf.
Now when I want to use the command
delete filename.txt I get the following message:

Is there a simple way to add all the variables currently in the workspace to a single structure? I'd prefer to have the name identifiers in the structure to be the same as the variable names in the workspace.
I know that whos will return a structure containing information on the ...

i made the following very simple model:
  --> fcn(u+2) ---> scope

and fed the output back to the function input.

Afternoon,
I have several scripts written in Matlab that each of them
runs alone, they are not functions. I would like to be able
to write a Matlab script that would run a series of Matlab

I am using Matlab R2008a on a Lenovo X60 Tablet with Dual
Core. I have a problem to start "matlabpool." For example,
if I run the following test code:

I have a string type variable, is it possible to use it in
the title of a figure or not?
Example
var_name = var_value;

Is there a matlab command for drawing multiple histograms on
a single figure like the subplot command?

How could I turn off latex interpreter in Matlab 2007b? I
remember that it is very easy to do so in old version
Matlab, just go to File->Preference. However, in 2007b I
can not find it.
