what is the plural of matrix
In mathematics, a matrix (plural matrices) is a rectangular array âof numbers, symbols, or expressions, arranged in rows and columns âthat is interpreted and manipulated in certain prescribed ways.atrices which have a single row are called row vectors, and those which have a single column are called column vectors. A matrix which has the same number of rows and columns is called a square matrix. A matrix with an infinite number of rows or columns (or both) is called an infinite matrix.
