How to number permutation values in "for" loop to be sequentially printed as 1, 2, 3 etc?

Hi. I have

a = [1 2 3]
b = [1 2 3]
c = [1 2 3]

I am running for loop for i = 1:3, j= 1:3 and m = 1:3. I need to print the output in terms of 1, 2, 3, 4, etc, instead of 111, 112, 113, 114, etc.

cnt = 0;
for ii = 1:3
    for jj = 1:3
        for kk = 1:3
            cnt = cnt+1
            ...
        end
    end
end

Thanks Stephen for the answer and suggestion,

Can I please ask to have it in a different form. For example, when I had two sets,

a = [1 2 3]
b = [1 2 3]

I used:

k= (i-1)*3 + j

Basically, I would like to modify this to suit three sets instead of two. Thanks again.

for ii = 1:3
    for jj = 1:3
        for kk = 1:3
            k = (ii-1)*3*3 + (jj-1)*3 + kk
            ...
        end
    end
end
