Summary: This paper is concerned with a recent conjecture of He (Electron. J. Comb. $14(1), 2007)$ on the spectral reconstruction of matrices. A counterexample is provided by using Hadamard matrices. We also give some results to the above mentioned conjecture (with slight modifications) in the positive direction.
Keywords: keywords reconstruction, Hadamard matrix
