Only change in it is, i've to convert constrained to unconstrained problem and solve by using unconstrained PSO algorithm. To convert this thing, i'm thinking to use Lagrangian Multiplier. But I'm not getting how to convert it using this.

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=fre...

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...

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...

Hello, I'm interested in constrained optimization in Matlab. I have a problem with constraints in my GA. For example: min f(x) = a* x1 + b*x2 + c*x3 where lb < x1,x2,x3 < ub and x1 + x2 + x3 > d. My GA can't find optimal minimum when bound "x1 + x2 + x3 > d" is active. In all constraints I use penalty (dynamic, static) Can anyone help me, how to deal with this constraint. Thanks Czarek Nowacki Hi, Are you sure that the constraints could be satisfied together. Post your problem as it is, so I can try to figure out why it's not working. Czar...

I have the following problems and no idea where to begin: 1) The function takes one string that contains two words separated by a space and returns true if the two words are identical (case sensitive).Otherwise, it should return false. Test Case: out1 = compareTwo('winner winner') out1 -> true 2) The function takes in a string which is a sentence of upper and lower case letters. The function then removes the upper case letters to reveal a secret message. The result should not contain any upper case letters. The result may contain lower case letters, spaces and numbers.
