QR Decomposition
Given a matrix 
, its 
-decomposition
is a matrix decomposition of
the form
 |
where 
is an upper
triangular matrix and 
is an orthogonal
matrix, i.e., one satisfying
 |
where 
is the transpose
of 
and 
is the identity
matrix. This matrix decomposition can be used to solve linear systems of equations.
QR decomposition is implemented in the Wolfram Language as QRDecomposition[m].
