Km×n
Km×n is a mathematical notation used to represent a grid or matrix with dimensions of k rows and n columns. The subscript 'm×n' signifies that the structure has 'm' horizontal lines and 'n' vertical lines, creating a total of m-1 rows and n-1 columns for cells. In some contexts, it can refer to a mathematical object with m rows and n columns, where the numbers within the grid or matrix are typically elements from a set, such as real numbers or integers. The notation is commonly encountered in linear algebra, computer science, and various areas of discrete mathematics. For example, a 3×2 Km×n would denote a grid with 3 rows and 2 columns, resulting in 2 rows and 1 column of cells. The term is a generalization of simpler grid notations.
