Row Echelon Form; Reduced Row Echelon Form - Casio fx-9860G Series User Manual

u Row Echelon Form
This command uses the Gaussian elimination algorithm to fi nd the row echelon form of a
matrix.
Example To fi nd the row echelon form of the following matrix:
Matrix A =
K 2 (MAT)6 (g )4 (Ref)
1 (Mat)av (A)w
u Reduced Row Echelon Form
This command fi nds the reduced row echelon form of a matrix.
Example To fi nd the reduced row echelon form of the following matrix:
Matrix A =
K 2 (MAT)6 (g )5 (Rref)
1 (Mat)av (A)w
# The row echelon form and reduced row
echelon form operation may not produce
accurate results due to dropped digits.
