The term "EP matrix" can refer to different concepts depending on the context. Here are a couple of interpretations: 1. **Eigenspace Projection (EP) Matrix**: In linear algebra, an EP matrix can be related to the projection onto an eigenspace associated with a specific eigenvalue of a matrix. The projection matrix is used to project vectors onto the subspace spanned by the eigenvectors corresponding to that eigenvalue.
