The exponential of a matrix A is defined by =!. Given a matrix B, another matrix A is said to be a matrix logarithm of B if e A = B.. Because the exponential function is not bijective for complex numbers (e.g. = =), numbers can have multiple complex logarithms, and as a consequence of this, some matrices may have more than one logarithm, as explained below.
The Matrix. (franchise) The franchise's logo that featured throughout its licensed merchandises. The Matrix is an American cyberpunk [1] media franchise consisting of four feature films, beginning with The Matrix (1999) and continuing with three sequels, The Matrix Reloaded, The Matrix Revolutions (both 2003), and The Matrix Resurrections (2021).
Observed information. In statistics, the observed information, or observed Fisher information, is the negative of the second derivative (the Hessian matrix) of the "log-likelihood" (the logarithm of the likelihood function). It is a sample-based version of the Fisher information.
The Matrix Resurrections is a 2021 American science fiction action film produced, co-written, and directed by Lana Wachowski, and the first in the Matrix franchise to be directed solely by Lana. It is the sequel to The Matrix Revolutions (2003) and the fourth installment in The Matrix film franchise. The film stars Keanu Reeves, Carrie-Anne ...

He betrays the crew of the Nebuchadnezzar, offering to give up Morpheus to the Agents in exchange for being inserted back into the Matrix with no memory of his time outside the Matrix.
Matrix (mathematics) An m × n matrix: the m rows are horizontal and the n columns are vertical. Each element of a matrix is often denoted by a variable with two subscripts. For example, a2,1 represents the element at the second row and first column of the matrix. In mathematics, a matrix (pl.: matrices) is a rectangular array or table of ...

The logarithmic norm is related to the extreme values of the Rayleigh quotient. It holds that. and both extreme values are taken for some vectors . This also means that every eigenvalue of satisfies. . More generally, the logarithmic norm is related to the numerical range of a matrix. A matrix with is positive definite, and one with is negative ...
