Hi, somebody can help saying me what blocks need, to convert the next code into SIMULINK and create a code C?
n = 50;
xy = 10*rand(n,2);
popSize = 60; numIter = 1e4;
showProg = 1;
showResult = 1;
a = meshgrid(1:n);
dmat = reshape(sqrt(sum((xy(a,:)-xy(a',:)).^2,2)),n,n);
[optRoute,minDist] = tsp_ga(xy,dmat,popSize,numIter,showProg,showResult);

you can use Embedded function ( called with recent versions: Matlab function)from Simulink/user defined function. But you have to check if all function are allowed by this block

thanks for you time Azzi, this example has help me to give me an idea, could you be kind to explain to me how I must declare the function DMAT, which is an array to calculate the distance point to point, this operation should be done in another block, or should I do it within the same block TSP?
any kind of information will be of great help, greetings!!!

Emmanuel, that depends on what you want to do with dmat, you use one matlab function or more, it's your choice. I can't tell because I do'nt know what exactly, you are doing? I will think about it

Hi, how to convert or to make blocks in simulink to do standard deviation using sliding window with the math script code ? T=2;F=1/T; t=linspace(-T,T,100); x =sin(2*pi*F*t)+0.5*randn(1,length(t)); subplot(2,2,1) plot(t,x) N = length(x); % length of the signal
% element count in each window n = conv(ones(1, N), ones(1, w), 'same');
% calculate s vector s = conv(x, ones(1, w), 'same');
% calculate q vector q = x .^ 2; q = conv(q, ones(1, w), 'same');
% calculate output values o = (q - s .^ 2 ./ n) ./ (n - 1);
% have to take the square root since output o is the % square of the standard deviation currently o = o .^ 0.5
