Matrices Key terms • augmented matrixA matrix obtained by appending the columns of two given matrices, usually for the purpose of performing the same elementary row operations on each of the given matrices. • cofactorThe signed minor of an entry of a matrix. • column vectorA matrix with a single column • determinantThe unique scalar function over square matrices which is distributive over matrix multiplication, multilinear in the rows and columns, and takes the value of 1 for the unit matrix. Its abbreviation is "". • determinantThe unique scalar function over square matrices which is distributive over matrix multiplication, multilinear in the rows and columns, and takes the value of for the unit matrix. Its abbreviation is "". • elementAn individual item in a matrix • identity matrixA diagonal matrix all of the diagonal elements of which are equal to , the rest being equal to . • identity matrixA diagonal matrix all of the diagonal elements of which are equal to , the rest being equal to . • inverse matrixA square matrix with an associated matrix such that multiplied by and multiplied by both equal the identity matrix. • inverse matrixFor a matrix , if a matrix exist such that multiplied by and multiplied by both equal the identity matrix, then is the inverse of . • linear equationA polynomial equation of the first degree (such as ). • matrixA rectangular arrangement of numbers or terms having various uses such as transforming coordinates in geometry, solving systems of linear equations in linear algebra and representing graphs in graph theory.
