21. Otherwise, a skew-symmetric matrix is just the same thing as a symmetric matrix. 22. Otherwise, a skew-symmetric matrix is just the same thing as a symmetric matrix . 23. This is conventionally represented by a 3? skew-symmetric matrix " A ". 24. The Cuthill McKee algorithm can be used to reduce the bandwidth of a sparse symmetric matrix . 25. Tr \ left ( A \ right ) denotes the trace of a symmetric matrix A. 26. Every symmetric matrix is thus, up to choice of an orthonormal basis, a diagonal matrix. 27. Where A \ succeq 0 indicates that a square symmetric matrix A is non-negative definite. 28. In quantum Mechanics the angular momentum L is often represented as an anti-symmetric matrix or tensor. 29. Moreover, a symmetric matrix " A " is uniquely determined by the corresponding quadratic form. 30. A symmetric matrix is a matrix whose values are symmetric in the northwest-to-southeast diagonal.
