**MATLAB algorithm to MATLAB function code or C code**hallo firends,
Can any body help me write this below code into MATLAB object oriented code or C code form please?

T0 = 1/f0; %fundamental AC period
T = M*T0; %Time for M periods (integer M)
N=30; % sample points per period.
dt = T0/N; % Sample at N points per period (integer N > 20)
t = dt*[1:M*N-1]; % Sampling time array
A0=120/2; % amplitude of AC signal. Divide by 2 or maybe sqrt (2) ?

**16QAM modulation MATLAB code**Hi,
I am facing a problem in generating a waterfall graph with the BER i calculate for each SNR value by using 16 QAM modulation. Instead of getting a waterfall graph, I get a straight line. Anyone can helps me?
It's urgent.
Hope to hear from you soon.
Thanks.
P.S : Please pm me so that we can have further discussion on my problem.

**frequency modulation simulation in matlab**i an doing an electronics project and would like to use matlab to
simulate what my hard ware is doing
basically what im doing is frequency modulating a sound wave onto the
mains 220v 50hz signal and transmitting it then the other end
recieving the 220v 50 hz signal and demodulating it to extract the
sound wave any tips on where i should look or some sample code would
be great i have little to know background to matlab so any help would
be greatly appreciated

**Frequency Modulation using Matlab**HEllo All,
I am having one querry regarding MATLAB.
What I would be doing is that I will give the signal from a microphone
and I have to use MATLAB so that the signal gets frequency modulated
and then I will be taking the output from the headphone jack and mix it
with a carrier frequency [Local Oscillator] and send it to the spectrum
analyzer.I am doing a project named (Software Radio) where you have to
do the signal modulation using Software
So could some one help with the code I have written below
it is giving the error.

Matrix dimensions must agree..

Hi Naveen,
i don't think you can do this. if you could, TMW would be
giving away the store! you can, however, use the MATLAB
Compiler to generate a DLL that you can call from C. MCC
will generate a little stub that you call. That stub will
call into the MCR (MATLAB Component Runtim...

**Killing the module from the own module code**I'v got a question about killing the module from it's own module code.
I''ve seen that some modules use OS_Module 4 to kill themselfs. For
example the module has a SWI which kill the module (like the ABImodule)
or a outcome of a service call kills the module. The SWI OS_Module
which kills the module is then 1 instruction away from the ending
instruction (like MOV PC,R14 or LDMFD R13,{....PC}) which ends the SWI
or ends the service call routine.
I think this coding is not right because after the module is killed the
area in which the module was stored is not anymore allocated....

**modules, modules, modules**Is it just me or do most Perl modules (Cpan) exist
outside of perl standard distribution? The phrase
"try this module" casually uttered here. Am I
mistaken, so many beta this and beta that listings.
If I put out a module on CPAN is it a guarantee
of fittness for any user of it? There is so much
crap and garbage out there on CPAN it makes my
head spin (Telnet being one). I've given up
on anything but in the official distribution.
Can anyone tell me why I've done that, or am
I just imagining things?

**MATLAB code to C code**Hi all
I read a similar question posted by someone else but my situation is
slightly different.
I am porting some MATLAB code to C code. I need to find a way to read
jpeg images in C just as imread does in MATLAB. The problem is that I
have tried a number of C libraries, but they do not serve my purpose
completely. I want to read simple grayscale jpeg images into unsigned
interger arrays.
Can someone pls shed some light.

**C code from MATLAB code**Hi
I have a complex algorithm that eventually will be encoded in C to
run on a DSP or Controller (e.g. Hitachi SH4). The present MATLAB
implementation under WINDOWS calls advanced standard MATLAB routines
such as fft, matrix factorizations, eigenvalue solvers, fmincon (for
nonlinear optimization subject to nonlinear constraints), and some
number theoretic functions. I figure that the transcription to an
optimized C code requires many months of hard labor. Before I embark
on this adventure, I would like to generate from my MATLAB code (as
easily as possible, i.e. as automatically as possible) ...
