CHAPTER 8: MATRICES and DETERMINANTS
kkuniyuk.com(Section 8.1: Matrices and Determinants) 8.07 3) Row Replacement (This is perhaps poorly named, since ERO types 1 and 2 may also be viewed as “row replacements” in a literal sense.) When we solve a system using augmented matrices, … We can add a multiple of one row to another row. Technical Note: This combines ideas from the Row Rescaling ERO
Performing Matrix Operations on the TI-83/84
betsymccall.netmatrices. Matrices in the TI-89/92 aren’t normally named; you can work with unnamed vectors. To enter the matrix from the augmented system we had above, you can enter the matrix in square brackets. Separate the entries by commas and use a semi-colon to break to the next row.
Exercises and Problems in Linear Algebra
web.pdx.edu(a)Use Gaussian elimination to put the augmented coe cient matrix into row echelon form. The result will be 2 4 1 1 1 a 0 1 1 b 0 0 1 c 3 5where a= , b= , and c= . (b)Use Gauss-Jordan reduction to put the augmented coe cient matrix in reduced row echelon form. The result will be 2 4 1 0 0 d 0 1 0 e 0 0 1 f 3 5where d= , e= , and f= .
