Orthogonal realizations of random sign patterns and other applications of the SIPP

Zachary Brennan, Christopher Cox, Bryan A. Curtis +4

A sign pattern is an array with entries in $\{+,-,0\}$. A matrix $Q$ is row orthogonal if $Q{Q}^T=I$. The Strong Inner Product Property (SIPP), introduced in [B.A.~Curtis and B.L.~…
