% make matrix hermitian
% ...
m = triu(A) + triu(A,1)'

No, Matlab was not tricked; I'm disappointed :); The result is according to the documentation!

The matrix, of course, is not positive defined but the documentation says:

"[R,p] = chol(A) for positive definite A, produces an upper triangular matrix R from the diagonal and upper triangle of matrix A, satisfying the equation R'*R=A and p is zero. If A is not positive definite, then p is a positive integer and MATLAB® does not generate an error. When A is full, R is an upper triangular matrix of order q=p-1 such that R'*R=A(1:q,1:q). ..."

% make matrix hermitian
% "... The chol function assumes that A is (complex Hermitian) symmetric. If it is not, chol uses the (complex conjugate) transpose of the upper triangle as the lower triangle ..."

m=triu(A); % [R,p] = chol(A) is the same as [R,p] = chol(A,'upper')
d = diag(m);
m = m + m';
s = size(m,1);
m(1:s+1:s*s) = d;
disp(m)

****
As implementation I guess that the algorithm used is the Bunch-Kaufman factorization of a symmetric matrix by ?sytrf routine ...

[...] = lu(A,'vector') still not work; please take a look at my workaround (with 'vector' the third output MUST be VECTOR)
Certainly, my code is valid only for full matrices.

I used mail address :)

Thanks !

:) wellcome!
