Who unified (i) electricity and (ii) magnetism so that electromagnetism is viewed as a single force type?

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

well clustered together.
