A transformation A ↦ P −1 AP is called a similarity transformation or conjugation of the matrix A. In the general linear group , similarity is therefore the same as conjugacy , and similar matrices are also called conjugate ; however, in a given subgroup H of the general linear group, the notion of conjugacy may be more restrictive than ...
The determinant of this matrix is −1, as the area of the green parallelogram at the right is 1, but the map reverses the orientation, since it turns the counterclockwise orientation of the vectors to a clockwise one. The determinant of a square matrix A (denoted det(A) or | A |) is a number encoding certain properties of the matrix.
By the Rouché–Capelli theorem, the system of equations is inconsistent, meaning it has no solutions, if the rank of the augmented matrix (the coefficient matrix augmented with an additional column consisting of the vector b) is greater than the rank of the coefficient matrix.
[1] Matrix multiplication was first described by the French mathematician Jacques Philippe Marie Binet in 1812, [ 2 ] to represent the composition of linear maps that are represented by matrices. Matrix multiplication is thus a basic tool of linear algebra , and as such has numerous applications in many areas of mathematics, as well as in ...
Weighing matrices are so called because of their use in optimally measuring the individual weights of multiple objects. [1] [2]In mathematics, a weighing matrix of order and weight is a matrix with entries from the set {,,} such that:
The Malaysian Matriculation Programme (Malay: Program Matrikulasi Malaysia) is a one-year pre-university preparatory programme [1] [failed verification] offered by the Ministry of Education, Malaysia.
The Matrix was released on DVD and Laserdisc in its original aspect ratio of 2.39:1 on September 21, 1999, in the US from Warner Home Video as well as in 1.33:1 aspect ratio in Hong Kong from ERA Home Entertainment. It was also released on VHS in both full screen and widescreen formats followed on December 7, 1999. [5]
The collagenases are No. 1, No. 8, No. 13, and No. 18. In addition, No. 14 has also been shown to cleave fibrillar collagen, and there is evidence that No. 2 is capable of collagenolysis. In MeSH, the current list of collagenases includes No. 1, No. 2, No. 8, No. 9, and No. 13. Collagenase No. 14 is present in MeSH but not listed as a ...
