L=1:10;
for k = L(~ismember(L,3:3:L(end)))
    k
end

A related way with a little more elegance:

N = 10;
for k = setdiff(1:N,3:3:N)
    k
end

Hmm. Or how about a while loop, with a variable step?

N = 10;
k = 0;
while k<N
    k = k + 1 + (mod(k,3) == 2);
    
    k
end

Or...

N = 10;
for k = sort([1:3:N, 2:3:N])
    k
end

There are always a milion ways to solve any problem in MATLAB. :)
