Loop is not looping

Hi guys, this is my final questions. So the objective of this program is to find all combinations of a, b, and c that equal zero. I want it to keep spitting out combinations until it's found all possible ones, but right now if I run it, it will either not get one and stop, or it will get a few and then stop. Here is the code:

F = [-5,-4,-3,-2,-1,1,2,3,4,5];
T = @(a,b,c) (a + b + c);
for m=F
a = randsample (F,1);
b = randsample (F,1);
c = randsample (F,1);
if T(a,b,c) == 0
disp ([a b c]);
end
end

Thanks for the help in advance.

Loop loops ten loops, but with ten there is a probability that no combination of a, b and c fulfills the condition.

How do I fix this so it repeats the loops if it doesn't full the condition?

    M = [];
    for ii = 1 : large_number
        .....
        if T(a,b,c)==0
            M = cat( 1, M, [a,b,c] );
        end
    end
    M = unique( M, 'rows' );

--- EDIT ---

function U = cssm( N )
    F = [-5,-4,-3,-2,-1,1,2,3,4,5];
    T = @(a,b,c) (a + b + c);
    M = [];
    for m = 1 : N
        a = randsample (F,1);
        b = randsample (F,1);
        c = randsample (F,1);
        if T(a,b,c) == 0
            M = cat( 1, M, [a,b,c] );
        end
    end
    U = unique( M, 'rows');
end

You decide what all combinations mean.

    U = cssm(1e4);

1e4 is that large enough to capture all combinations?

I take it the dots are where I put my original code?

[Nathaniel Ewing]

I'm not sure how I would use the M in this situation, or Concatenate arrays. Could you explain a bit please? Thanks!

Yes this works perfectly, thank you very much for your help.
