<p style="text-align: justify;">The concept of secondary range Hermitian ( s-EP ) matrices is introduced as a generalization of s-Hermitian and EP matrices. Necessary and sufficient conditions are determined for a matrix to be s-EP<sub>r</sub>( s-EP and rank r ) Equivalent characterizations of a s-EP matrix are discussed. As an application, it is shown that the class of all EP matrices having the same range space form a group under multiplication.</p>
