  • M=pop(randi(size(pop,1)),:)
  • now i want to know that how to delete this M without knowing the row number and the values of the row, just to delete it by using The "M"

Best Answer

This depends on M being exactly equal in each of its elements to the corresponding elements of one of the rows of 'pop':
for k = 1:size(pop,1)
  if all(M==pop(k,:)
    pop(k,:) = []; % Delete the matching row of pop
    break;
  end
end
