**Help Needed on Matlab Code to Generate Orthogonal Codes**I am new to matlab but I need code urgently to pass my final year
project. The project intends to compare Walsh-Hadamard and Gold codes.
The matlab code should do the following:
----------------
PART ONE:
----------------
(1) generate random message bits
(2) generate walsh-hadamard codes
(3) modulate the signal
(4) transmit the spreaded signal
(5) plot the message and walsh-hadamard codes as rectangular pulses;
also plot the spreaded signal, with labels on plots.
(6) on the same figure, do the reverse, i.e plot the demodulated,
de-spreaded signal, just as it was shown at the transmitter side....

**Matlab code to C-code generation using emlc**Hi,
I am trying to convert my matlab code to C-code using the emlc command (of embedded matlab). Upon execution,I realize the following problems-
1. Many .c and header files are generated, how to compile them is an issue for me...
2. A lot of header files are not found when I try to compile the files using Dev-Cpp
3. No main function is generated resulting in the error- invalid reference to win32@16
Kindly help. Thanks a lot in advance.

**Can you use zlib from Matlab, only using native Matlab code?**Hello,
I'm trying to decompress a file using zlib, for use by my Matlab function. Currently I'm doing it by calling Python midway through my function, but I would like to make it so that I don't need to have Python installed on whatever computer I'm trying to run my function on.
I was wondering if there was a way for me to use zlib just using native Matlab code. I don't know much about compression/decompression, so I'm open to any suggestions. I've been searching around for a while, and haven't found anything.
Thanks very much

**Precise signal generation using matlab**Can I generate a signal using MATLAB which is in the order of microseconds( Stays low for 1microsecond and becomes high the next microsecond) and output the same via serial or parallel port?

*Maybe*. I personally wouldn't count on it, though.
You _might_ be able to do an acceptable job of timing a signal if you

I am student and I have devlop one small module in matlab (.m file)
but my other module is in vb so I want to add my matlab module in vb.
So please guide me that how can I use matlab module in vb (or vb.net)
Waiting for your kind,quick reply.
Yours,

You should look into the Matlab comtool which can compile your matlab
functions into an COM dll which you then can call from your VB code
ook in the MAtlab help under MATLAB COM builder

**C Code generation using Embedded MATLAB**Hi,
Is there any workarounds to generate C-code using Embedded MATLAB for variables whose size is know only at run-time and hence memory allocated dynamically. A simple case would be to generate the code to determine the median of a certain number of points, the number of points being known only at run-time. To avoid dynamic memory allocation, suppose I use a worst case size scenario of 4096 data points, the code generated by Embedded MATLAB is specific to this size. I cannot use this generated code to determine the median of, say 4095 points, because the way median is determined is different...

Well get a toolbox (netlab or nn toolbox) and start writing code using
functions in the toolbox! This since every case is different. for instance
the outpu in your case... or the format of pictures, the need for

**about Matlab generate C code which can be used in C5505**Hey
i found out that matlab can use simulink to build CCS project and it can optimize the code corresponding to the different DSP.
Here is the following question.
i found out that matlab only support one chip which is C5510 DSK in C55XX series. however, i checked the driver for my TMS320C5505 EVM board, it is C5510 DSK.
So, can i use matlab to generate CCS project for my TMS320C5505?
my second question is: why the driver which installed for my TMS320C5505 EVM board is C5510.
Best regards
Reynold
