The angular correlation function describing the decay products of $\ensuremath{\Lambda}$ and $\ensuremath{\omega}$ in the reaction ${K}^{\ensuremath{-}}+p\ensuremath{\rightarrow}\ensuremath{\Lambda}+\ensuremath{\omega}$ is analyzed and expressed in terms of production matrix elements. It is shown that, with unpolarized target, aside from two phase factors all production matrix elements can be determined from angular correlations. With polarized target, the production matrix elements may be completely determined up to an over-all phase factor. In addition, with polarized target the $K\ensuremath{-}\ensuremath{\Lambda}$ relative parity may be directly measured.
