If is real, then and can be guaranteed to be real orthogonal matrices; in such contexts, the SVD is often denoted . The diagonal entries σ i = Σ i i {\displaystyle \sigma _{i}=\Sigma _{ii}} of Σ {\displaystyle \mathbf {\Sigma } } are uniquely determined by M {\displaystyle \mathbf {M} } and are known as the ...
The singular values are non-negative real numbers, usually listed in decreasing order (σ 1 (T), σ 2 (T), …). The largest singular value σ 1 (T) is equal to the operator norm of T (see Min-max theorem). Visualization of a singular value decomposition (SVD) of a 2-dimensional, real shearing matrix M.
In linear algebra, the generalized singular value decomposition (GSVD) is the name of two different techniques based on the singular value decomposition (SVD).The two versions differ because one version decomposes two matrices (somewhat like the higher-order or tensor SVD) and the other version uses a set of constraints imposed on the left and right singular vectors of a single-matrix SVD.
Some aspects can be traced as far back as F. L. Hitchcock in 1928, [1] but it was L. R. Tucker who developed for third-order tensors the general Tucker decomposition in the 1960s, [2] [3] [4] further advocated by L. De Lathauwer et al. [5] in their Multilinear SVD work that employs the power method, or advocated by Vasilescu and Terzopoulos ...
The conjugate transpose of a matrix with real entries reduces to the transpose of , as the conjugate of a real number is the number itself. The conjugate transpose can be motivated by noting that complex numbers can be usefully represented by 2 × 2 {\displaystyle 2\times 2} real matrices, obeying matrix addition and multiplication:

The original Sword of State of South Carolina (early 18th century) was used from 1704 to 1941, when it was stolen. [62] [63] A replacement Sword of State of South Carolina (1800) was used between 1941 and 1951. It was a cavalry sword from the Charleston Museum and was used in the War of 1812 and the American Civil War. [62]
Playing the legendary sword-fighting vigilante in 1998’s The Mask of Zorro was deeply impactful for star Antonio Banderas, the now 62-year-old Spanish actor told us in a recent interview.
