Welcome to Omni's QR decomposition calculator! Here you can determine the QR decompositions of square and rectangular matrices. Not sure what the QR decomposition or QR factorization is? We will give you the definition of the QR decomposition for square matrices and tell you how it extends to rectangular matrices with more rows than columns. We will explain how to find the QR decomposition and we will discuss the main application of the QR factorization, that is, how it can facilitate solving systems of linear equations. At the very end there will be, of course, a detailed step-by-step example of QR decomposition. Let's go! Decomposition or factorization of a matrix is the process of representing this matrix as a product of two or more matrices that have various special properties. The idea is that various matrix operations become simpler thanks to the special properties of constituent matrices. There are lots of different types of matrix decompositions; among the most popular types there is the QR decomposition, which is the topic of this page, as well as the LU decomposition , Cholesky decomposition , and the singular value decomposition SVD. In the QR decomposition, we factor a real square matrix A of size n x n into the product of two matrices:. If A is invertible and we require the diagonal entries of R to be positive, then the QR decomposition is unique.

In such a case, the QR decomposition is not unique. In the QR decomposition, we factor a real square matrix A of size n x n into the product of two matrices:. Matrix size. Another important field where QR decomposition is often used is in calculating the eigenvalues and eigenvectors of a matrix. Yes, every square matrix and even rectangular matrix has a QR decomposition. Equivalent Fractions Calculator. There are several methods for deriving the QR decomposition of a matrix: Gram—Schmidt orthogonalization - this method is easy to understand even with only basic knowledge of linear algebra, but it's numerically unstable and so not very useful in real-life applications. Equivalently, you can determine R by left-multiplying the original matrix A by the transpose of our newly-found matrix Q as follows:.
