Webpage 1 . 2.1 Matrices. Defs. A matrix is a table of entries (usually numbers). It is denoted by a capital letter such as A. The plural of matrix is matrices. Rows run horizontal. The elements on the diagonal of a skew-symmetric matrix are zero, and therefore its trace equals zero. If A {\textstyle A} is a real skew-symmetric matrix and λ {\textstyle \lambda } is a real eigenvalue , then λ = 0 {\textstyle \lambda =0} , i.e. the nonzero eigenvalues of a skew-symmetric matrix are non-real.
