Linear Algebra and Matrices: Least-Squares Solution and Normalized Error

Find the least squars solution of Ax=b, retaining five places to the right of the decimal point. Finally, verify that your least squares solution satisfies the least-squares problem and calculate the normalized error e=E/ lbl.

A: ( 0 8 -1 )
( 1 2 0 )
( 0 0 3 )
( 0 4 5 )

(represents a single matrix)
