QR Decomposition without Pivoting

Given the matrix
X
of size LaTex Math image. , the problem is to compute the QR decomposition LaTex Math image. , where
  • Q
    is an orthogonal matrix of size LaTex Math image.
  • R
    is a rectangular upper triangular matrix of size LaTex Math image.
The library requires LaTex Math image. . In this case:
LaTex Math image.
where the matrix LaTex Math image. has the size LaTex Math image. and LaTex Math image. has the size LaTex Math image. .
