The MATRIX program is designed to perform and to teach row operation algorithms on matrices. The program can work in a decimal floating-point mode in which calculations are carried out to 18 significant digits, or it can work in a fraction mode with exact rational arithmetic.
In mathematics, a matrix (plural matrices) is a rectangular array âof numbers, symbols, or expressions, arranged in rows and columns âthat is interpreted and manipulated in certain prescribed ways. square matrix is a matrix with the same number of rows and columns.
