Fitting N(N-1) points on an NxN matrix

Suppose I have an N(N-1) vector that corresponds to each non-diagonal entry of an NxN matrix. Is there anyway that I can encode that onto my matrix?

i.e. For n=3, given [ 2 3 4 5 6 7 ] we obtain

[0 4 6 ; 2 0 7 ; 3 5 0]?

If one posts same question here and at another forum at the same time, like comp.soft-sys.matlab, it is only right that you mention that and give a link. This way one does not waste their time if someone else already answered you on the other forum.

I didn't know how that happened... but thanks for letting me know

% Say your given vector is:
X = [ 2 3 4 5 6 7 ];

% Now to make the matrix.
L = (1 + sqrt(1+4*length(X)))/2;
F = double(~eye(L));
F(~eye(L)) = X
