MATLAB: Evan, if I want to return back

genetic algorithmMATLABstring to number

Dear, If I want to return back again the solution in GA which is string to fife numbers after applying it, suppose this is the string, I want to return the points in their position for example

0028023482100090411607002407264000021081060000000698132 to

[28.234821 , 9.411607 , 24.726400 , 21.810600 , 0.698132] don't forgot I deal with fixed matrix [20,5] and in the future it will be with random population

thanks

Disclaimer: Not having experience with GAs myself, I can offer something that will make what you're wanting to do work, but I have no knowledge of how convenient, accurate or efficient it will be for your purposes.

s = '0028023482100090411607002407264000021081060000000698132';
m = reshape(s,11,[])';
v = [str2num(m(:,1:4)) + str2num(m(:,6:end))/1e6]';

I think you might want

name=strcat('d',dstr,'_',num2str(randi(100)));

This will convert the number to its string equivalent, rather than the ASCII value corresponding to that value (which is what I assume is happening now).

You can use bwconncomp. See this demo I wrote for you:

U3(:,:,1) = [
0 , 0 , 0 , 0 , 0;
0 , 0 , 0 , 0 , 0;
0 , 1 , 0 , 0 , 1;
0 , 0 , 0 , 0 , 0;
0 , 0 , 0 , 0 , 0
]
U3(:,:,2) = [
0 , 0 , 0 , 0 , 0;
0 , 0 , 0 , 0 , 0;
0 , 1 , 0 , 0 , 1;
0 , 1 , 0 , 0 , 0;
0 , 1 , 0 , 0 , 0
]
U3(:,:,3) = [
0 , 0 , 0 , 0 , 0;
0 , 0 , 0 , 0 , 0;
0 , 1 , 0 , 0 , 1;
0 , 0 , 0 , 0 , 0;
0 , 0 , 0 , 0 , 0
]
% Method 1
% Make the list for how you want the objects labeled:

desiredNumberList = [2 3 4 42 69 123 73]; % Whatever you want.

% Make an object for the output
labeledImage = zeros(size(U3), 'int16')
% Do connected components labeling.
connectivityObject = bwconncomp(U3)
% Get the number of object it found (optional).
numberOfObjects = connectivityObject.NumObjects
% Now go through the blobs, reassiging them with the labels Hisham wants.
for blob = 1 : numberOfObjects
  % Get the linear indices of the pixels that
  % identify this particular blob.
  pixelIndexes = connectivityObject.PixelIdxList{blob}
  % Make those pixels have the desired number.
  labeledImage(pixelIndexes) = desiredNumberList(blob);
end
% Print out the output image to the command window.
labeledImage
% Method 2
% Use labelmatrix but cast to uint16 if you ever expect to have more than 255 blobs.
labeledImage = uint16(labelmatrix(connectivityObject))
% But you didn't want 1,2,3, etc.  You wanted custom numbers.
% For that we need to remap the default label numbers using intlut().
% Right now the blobs are labeled 1,2,3, etc.
% Make those pixels have the desired number with intlut().
% Make the list for how you want the objects labeled:
% But first one has to be zero because zero must remain as zero.
desiredNumberList = zeros(1, int32(intmax('uint16'))+1, 'uint16');
desiredNumberList(1:8) = [0 2 3 4 42 69 123 73]; % Whatever you want.
labeledImage = intlut(labeledImage, desiredNumberList)
