How to save multiple 3x1 matrixes in one big matrix?

I have this code so far

for F = 100:500

A = [2/7, -1.5/6.5, -1/3; 3/7, 2/6.5, -2/3; -6/7, -6/6.5, -2/3];

B = [0; 0; -F];

X = A\B;

end

And I get a 3x1 matrix for X and I was trying to figure out how to save all the values into one big 3x400 matrix but can't figure it out any help would be appreciated.

How about:

f = 100:500;
X = nan(length(f),3);

A = [2/7, -1.5/6.5, -1/3; 3/7, 2/6.5, -2/3; -6/7, -6/6.5, -2/3];
for i = 1:length(f)
    F = f(i);
    B = [0; 0; -F];
    X(i,:) = A\B;
end
X

X = 401×3
