...soft decoding of conv. codes using vitdec matlab func. #2
Isnt 'unquant' and 'soft' options essentially same?..in both case
vitdec takes in "real numbers" as input (ok they are "mapped" in case o
'soft' option)..so can we not use 'unquant' option to carry out sof
decoding?...my preliminary results show that 'unquant' option give me 2-
db gain over hard decoding...
any one having insight please let me know.

...matlab in JAVA or java in MATLAB? #2
I am now experencing a great difficulty in the interation between java and matlab.
I have an objective function written in JAVA with has method return an numerical number, i call it 'profit'. The nature of this obtive function (ObjFun.java) is that it takes an parameter input, say C, with different C value, the returned profit value is different.
Eventually I want to find the optimized C value which produce the maximun profit (C will be under constrains). Initially I want to use linprog or fminsearch in matlab. So I tried the command in matlab that excutes my ObjFun.ja...can Matlab support 32-bit matlab version scripts on 64-bit version of matlab #2

...HIPERLAN/2 PHY layer simulator on Matlab #2
ur answer could be right if I apply the effect of the channel to the
signal then i add the noise, but what i do is adding the noise efect
first then applying the channel effect to the sum (signal+noise), to
channel*(signal+noise), so after equalization i'd have --->
(channel*(signal+noise))/channel -- > signal+noise.
hope u got what i mean .!
thanks alot Laki for ur participation
That's an interesting way to model the system, but i'll come back to
What I think you're trying to do is this

I am trying to implement a C++ code with mex function in Matlab. The code is written to generate a stochastic process. If I compile the code under Cygwin with g++ command,
the simulation works fine. But if I compile it in Matlab (I tried both VC9.0 and Watcom) and run it in Matlab, it always generate some Infinite numbers. I am not quite an expert in C++, so I am not sure what could be the problem. Could someone help me out here?
The code is long, so I won't post it, but you can find it here: http://people.math.jussieu.fr/~tankov/code/
Thanks a lot for any help

I am trying to run a simulink model simulation in definite time steps from MATLAB so that I can extract data from simulink, do some caluclations and send these new data back to Simulink for further simulation from the point I left off.
The process can be descirbed below:
Note that total simulation time is 600 seconds.
1. Start simulation from MATLAB for 100 seconds and then pause the simulation
2. Extract all the data I need from simulink and bring into MATLAB, do some calculations to changes simulink model parameters and then pass this new calculated data back to simulink.
3. Continue th...EngSim: All Matlab features and functions. 2 to 20 Times Faster than MATLAB. Use the same programming syntax as MATLAB, ANSI C/C++, /C++. Good Graphics.

...I cant compile a matlab function in simulink. Matlab 2012b, OSX 10.8.2, xcode 4.5.2
I haven't been able to compile a Matlab function in a Simulink model. I am using Matlab 2012b, OSX 10.8.2 and Xcode 4.5.2.
I have already run the patch for Xcode 4.5.2 and also verified that
in the mexopts.sh file.
When simulink tries to compile the function I get the error message:
/usr/llvm-gcc-4.2/bin/../lib/gcc/i686-apple-darwin11/4.2.1/include/limits.h:15:25: error: no include path in which to search for limits.h
Any ideas how to fix this.
...MATLAB talking to MATLAB?
For my project, I need to have a client program (MATLAB executable) talking
to a server program (also MATLAB executable) to query data. Is there any
easy way to accomplish that?
I appreciate any help that I can get on that.
Oops, I forgot to mention. There are multiple clients querying the server,
so I guess serial objects + remote serial port wouldn't work.

I think you need the function evalfis()
...softly interrupting a MATLAB function
Does anyone know if there is a way to interrupt a long-running MATLAB
function in such a way that one can execute a separate set of
commands in a "catch"-type environment? Basically, I'd like to
combine Cntl-C with error trapping, so that Cntl-C executes a catch
block (i.e., try-catch-end), since it doesn't occur naturally.
I have done something similar to this in a GUI environment, but in
this case, it is in batch mode.

...Matlab help Matlab – VaR #2
I was just wondering if somebody knew how to do this. I know of the function gevrnd but have know clue how to generate this.
question: In Matlab, create a vector with 10,000 random returns, which follow the generalized extreme value distribution with a mean return of 8% and standard deviation equal to 2.5%. Assume the tail index equals 0.09. Then assume that these are true historical returns. Find the historical simulation VaR figure for a 5% significance level. Then repeat the exercise using normally distributed random numbers and comment on your results.

Is there any limitation to run Matlab from Matlab, as a system command, on Linux platforms ?
I tried to start Matlab, both using the ! syntax (!matlab&) or the system command (system('matlab&')), the Matlab splash screen appears, but the new Matlab session closes rapidly .
When I do the same with a script of mine (system('matlab -r "myscript"&')), my script is being executed, but Matlab finally crashes .
If I remove the &, it works well, but the first Matlab session is blocked till I close the second one .
