Intro to matrices (article)
Matrix elements. A matrix element is simply a matrix entry. Each element in a matrix is identified by naming the row and column in which it appears. For example, consider matrix G : G = [ 4 14 − 7 18 5 13 − 20 4 22] The element g 2, 1 is the entry in the second row and the first column . In this case g 2, 1 = 18 .
Decision Matrix Analysis
Decision Matrix Analysis helps you to decide between several options, where you need to take many different factors into account. To use the tool, lay out your options as rows on a table. Set up the columns to show the factors you need to consider. Score each choice for each factor using numbers from 0 (poor) to 5 (very good), and then allocate ...
Matrices
A matrix is a rectangular array of numbers, variables, symbols, or expressions that are defined for the operations like subtraction, addition, and multiplications. The size of a matrix (which is known as the order of the matrix) is determined by the number of rows and columns in the matrix.The order of a matrix with 6 rows and 4 columns is represented as a 6 × 4 and is read as 6 by 4.
