hallo firends, Can any body help me write this below code into MATLAB object oriented code or C code form please? M=50; % total number of periods. (choose for 1s duration) f0 = 50; % fundamental AC frequency 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) ? AC=A0*sin(f0*t*2*pi); % create AC signal. DC0=50; % DC amplitude DC=DC0*ones(1,length(t)); % create a DC signal that is constant of length t S=AC+DC; % total signal is AC signal + DC signal figure(1); plot(t,S); % plot signal. xlabel('time');ylabel('Signal'); title('Total Signal'); % filter components fAC=S-mean(S); % here is the AC component fDC=mean(S); % here is the DC component figure(2); plot(t,fAC,'r',t,fDC,'b'); % plot AC and DC signals legend('AC','DC'); xlabel('time');ylabel('Signal'); title('Signal with only AC component'); figure(3); plot(t,fDC,'b'); % plot DC signal legend('DC'); xlabel('time');ylabel('Signal'); title('Signal with only DC component'); figure(4); % best to plot in Fourier domain u=abs(fftshift(fft(S))); NumPoints=length(t); freq=(1/dt)*[1:NumPoints]/NumPoints; % create frequency axis freq=freq-max(freq)/2; % center about 0 plot(freq,u); xlabel('frequency');ylabel('signal'); title('Fourier transform'); with best regards, Gopal

im working on a project using matlab. i want to use some of the already writen codes in C++. i want to use these codes in my project rather than writing them from scratch. is there some way or a chunk of code that might convert C++ code to matlab code or a ".c" file to ".m" file. please if anyone knows do let me know at the earliest.thanks "fatima " <fatima_naseem2002@yahoo.com> wrote in message <i8ugqn$e9p$1@fred.mathworks.com>... > im working on a project using matlab. i want to use some of the already writen codes in C++. i want to use these c...

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. Thanks Qaseem ...

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) ...

If I want to generate C-code from m-file not specifically for embedded target, which tool can I use? As of I know emlc converts embedded MATALAB code to C-code. Does the Real-Time Workshop uses emlc? Please any one tell me how can I convert my m-file (not only embedded m-file) to C- code. 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...

Hi, I am learning to call Matlab code from C/C++ code. Here are my questions (1)are using Matlab engine and converting Matlab code into a C or C++ shared library the only two ways?

Hi, Folks I have written some matlab functions (Matlab 6.5), and I want to change them into visual c++ or c codes then create a visual c++ project to use the generated c++ or c codes.(visual c++ 6.0). Could anyone give me the full instructions on how to deal with it because I have met some unresolved external symbol problems when linking (use visual c++ 6.0). Have I missed to include some lib files? Thanks.

Is it possible to read C/C++ code in matlab and the other way around too? Hi, as long as C or C++ are written in text files you can edit them in the matlab editor. To see the special character of C or C++ coding language, in the editor go to menus: file>preferences>Edito/Debugger>language and on popup "Language" select "C/C++". This does not allow you to run the C/C++ code, just to view it i nicer way... regards, chris saneman <asdfsdf@asd.com> wrote in message <frl846 $f8i$2@news.net.uni-c.dk>... > Is it possible to read C/C...

I made a program which consists of tens of .m files and I found some parts of this program are making the whole program slow. I want to replace those time-wasting parts with C++ codes. I think C++ codes are a bit faster than MATLAB codes. :) Is this possible? If possible, can anybody teach me how to do this? (Or, If there's other way to improve the speed, please let me know.)

Hi, Is there any method avilable to convert MATLAB code into C code for perticular application of ANN. Regards, Manoj Manoj wrote: > Is there any method avilable to convert MATLAB code into C code for > perticular application of ANN. Yes: use one or more humans to rewrite the code. If you are looking for automated methods, then it depends upon which Matlab version you are using, but chances are that if you are using a Matlab version old enough to be compilable to C then it probably doesn't support the Neural Network toolbox. Are you sure you need to convert...

Dear friends, I have a Matlab code to process a pure analog signal 'u'. Now I want to implement it in Simulink and I want to use it in 'Embedded Matlab fun block' so i need to transform 'Matlab code' to 'Embedded Matlab fun code' to perform the task. The Matlab code is as follows: %%%%%%%%%%%%%%%%%%%%% u_abs = abs(u); major_th = 1.5e-1; minor_th = 1.8e-2; major_peak_value = []; minor_peak_value = []; pos = 1; pos_max = 1; while ~isempty(pos) [m pos_max(end+1)] = max( u_abs( pos : pos + 10) ); pos...
