function [popnew1,mutated] =mutation(A,Pm)
mutated = find(rand(size(A))<Pm);   
popnew1 = A;
% Why my this condition is not working
if A(mutated)== 1
   popnew1(mutated) = 2-A(mutated);
else
   popnew1(mutated) = 1-A(mutated);
end
%
end

Please Help me why my this condition part is not working Where A is 3x8 matrix and Pm=0.1 .

Where is the problem in my condition ?

if A(mutated) == 1
   popnew1(mutated) = 2-popnew1(mutated);  % in place of A put popnew1
else
   popnew1(mutated) = 1-popnew1(mutated);  % in place of A put popnew1
end
