Some authors use the term Gaussian elimination to refer to the process until it has reached its upper triangular, or (non-reduced) row echelon form. For computational reasons, when solving systems of linear equations, it is sometimes preferable to stop row operations before the matrix is completely reduced.
To solve by the Gaussian-Jordan Elimination method, use the rref(, reduced row-echelon form method. Press MATRIX, right arrow to get to MATH, and down arrow to rref(, and ENTER. With rref(on the screen, return to the matrix menu to obtain Matrix A and press ENTER. The third column of rref ([ A ]) is 2.8, 0, and 0.2.The matrix is in reduced row-echelon form.o find det(A), press MATRIX and the right arrow to highlight MATH. Press number 1, MATRIX, number 1, close), and ENTER. det([A]) = -1. Adding and Multiplying Two Matrices. Matrix D as shown to the right was stored in the TI-83. To add matrix A and matrix D, press MATRIX, number 1, +, MATRIX, number 4, and ENTER.
