Hello I am a student n i want to write a program which takes input as a matrix of any dimension and returns an array of its elements but they should be unique. element's appearance should be once only. I have written a small code but it is showing req output. The code is:
mat=rand(1,6) copy1(1)=mat(1) for i=2:length(mat) for j=1:length(copy1) if (mat(i)~=copy1(j)) copy1(i)=mat(i); else break; end
end
end
Kindly help....
