the whole sentence is: "what & # 39; s up?” American oral English is a popular greeting in recent years
it sounds like & quot; SUP" The pronunciation of English
for the convenience of typing in chat rooms, we use & quot; SUP" Instead of what & # 39; s up?< Other meanings of sup include: 1. Abbreviation of supplement, N. supplement, supplement; 2; Vt. supplement, supplement. For example: X & # 179; Represents x ^ 3 (the cube of x)
2. Stand up paddle is the abbreviation of English standing up paddle
3. Some subtitle file extensions. These files are usually data files with special purpose, which are not allowed to be opened by other tools except the program files that generate them
4. It is also a game term. Sup -- support (auxiliary hero) is the auxiliary hero in the game League of heroes
5. Mathematically, sup {} is used to denote "Supremum", that is, the minimum upper bound.
1) for any x ∈ e, X ≤ β What does this sentence mean β Is the upper bound of E)
2) for any α> 0, there exists at least one X ∈ e such that x > β-α, That is, any less than β The number of β-α It must not be the upper bound of E
then let's say β Is the supremum of e
denoted as
β
=
sup
e
similarly, the definition of infimum, which is symmetric to supremum, exists, and is expressed by inf, which is the abbreviation of infimum.
With any M × N matrix G can be decomposed into g = uwv < sup > T < / sup >. Where u is m × R matrix; V is n × R matrix; W is r × R diagonal matrix, except diagonal, all other elements are zero < sup > [1] < / sup >, namely
geophysical inversion course
in equation (4.4): R is the rank of matrix G; δ< sub>1≥ δ< sub>2≥…≥ δ< Sub > R < / sub > is the singular value of a matrix, which is the positive root of R nonzero eigenvalues of G < sup > T < / sup > G or GG < sup > T < / sup >
u is m of GG < sup > T < / sup > × R eigenvector matrix, V is n of G < sup > T < / sup > G × R eigenvector matrix. They are semi orthogonal matrices < sup > [1] < / sup >:
U < sup > T < / sup > u = I < sub > R < / sub >, V < sup > T < / sup > V = I < sub > R < / sub >, UU < sup > T < / sup > ≠ I < sub > R < / sub >, VV < sup > T < / sup > ≠ I < sub > R < / sub > (4.5)
where I < sub > R < / sub > is the identity matrix of order R
When the singular value is large, G is a nonsingular matrix with generalized inverse matrix:G < sup > - G < / sup > = VW < sup > - 1 < / sup > U < sup > T < / sup > (4.6)
where:
