In mathematics, especially in linear algebra and matrix theory, the duplication matrix and the elimination matrix are linear transformations used for transforming half-vectorizations of matrices into vectorizations or (respectively) vice versa.
ÉLECTRE is a family of multi-criteria decision analysis (MCDA) methods that originated in Europe in the mid-1960s. The acronym ÉLECTRE stands for: ÉLimination Et Choix Traduisant la REalité ("Elimination and Choice Translating Reality").

Health insurance industry officials remain uncharacteristically reserved in the aftermath of the fatal shooting of UnitedHealthcare CEO Brian Thompson on Dec. 4.. A week after the attack, the ...
In linear algebra and numerical analysis, a preconditioner of a matrix is a matrix such that has a smaller condition number than . It is also common to call T = P − 1 {\\displaystyle T=P^{-1}} the preconditioner, rather than P {\\displaystyle P} , since P {\\displaystyle P} itself is rarely explicitly available.
The U.S. Supreme Court issued several major decisions over the course of 2024.. Its rulings include those that have pushed back on the Biden administration's attempted change of Title IX ...
