How would I write this code without using loops?

x57a= [];
for i= 1:1000
    if rem(i,5) ==0 || rem(i,7) ==0 
        if rem(i,5)==0 && rem(i,7) ==0 
            continue;
        end
        x57a = [x57a, i]; 
    end 
end

I wrote this for loop that gives me the multiples of 5 and 7 (but not both) in 1 to 1000, but I am having trouble rewriting it using indexing or even the find function. I just don't want to use loops

I don't get what you want to do.

Can you elaborate on it a bit more?

Answer 1

[KSSV]

i = 1:1000 ;
O = zeros(size(i)) ;  
idx1 = rem(i,5)==O | rem(i,7)==O ; 
idx2 = rem(i,5)==O & rem(i,7)==O ;

iwant = find(idx1 ~= idx2) ;

Another option:

N = 1000;
five = 2*5:5:N;
seven = 2*7:7:N;

res = setxor(five,seven)
