This MATLAB function returns the upper-triangular R factor of the QR decomposition A = Q*R.

Calling qr for numeric matrices that are not symbolic objects (not created by sym, syms, or vpa) invokes the MATLAB ® qr function. Matrix computations involving many symbolic variables …

The QR Factorization block uses a sequence of Householder transformations to triangularize the input matrix A.

The qrinsert function returns a valid QR factorization. However, the factorization results may vary if you explicitly insert the row into the original matrix and then calculate its QR factorization …

This MATLAB function when [Q,R] = qr (A) is the original QR factorization of A, returns the QR factorization of A + u*v', where u and v are column vectors of appropriate lengths.

In contrast to the LU factorization, the QR factorization does not require any pivoting or permutations. But an optional column permutation, triggered by the presence of a third output …

The algorithm used in this example is the QR factorization implemented via CORDIC (Coordinate Rotation Digital Computer). This example shows how to write MATLAB® code that works for …

Using a matrix from the MATLAB Gallery collection as an example, this article discusses three variants of the QR algorithm available in MATLAB.

Apr 7, 2021 · Currently RQ, QL, and LQ factorizations are not included in Matlab, although these factorizations can also be done by QR function and additional matrix manipulations if matrix is …
