I want to find the maximum sum in a 2D matrix such that: You can pick only 1 element from each row You cannot pick a column that has been picked before. Example: matrix = [ [12, 1, 1, 1], [13, 10, 1, 1], [40, 1, 1, 12] ] Solution: We pick 12 from 1st row Now w...
We further determine the commutative reduced rings over which every n × n matrix is a sum of two tripotents.doi:10.1080/00927872.2020.1849249Xia, GuoliTang, GaohuaZhou, YiqiangCommunications in Algebra

In a matrix data region with nested row groups Category and Subcategory, and nested column groups Year and Quarter, in a cell that belongs to the innermost row and column groups, the following expression evaluates to the maximum value from all quarters for all subcategorie...
The trace (tr) of a matrix is defined as the sum of the elements along the leading diagonal. Let =(pmatrix) a&b c&(pmatrix) and =(pmatrix) e&f &h(pmatrix) .Hence prove that, if there exists a non-singular matrix such that P^(-1) (MP)=(pmatrix) p&0 0&q(pmatrix) the...
The purpose of this paper is to introduce a two-person zero-sum matrix game in which the payoffs are characterized as fuzzy random variables. Based on fuzzy random expected value operator, a fuzzy random expected minimax equilibrium strategy to the game is defined and the existence of the stra...
