This application decomposes an $m\times n$ real or complex matrix $A$ into the form \[ A=QR, \] where $Q$ is an $m\times m$ orthogonal matrix or unitary matrix, if $A$ is a complex matrix, and $R$ is an $m\times n$ upper triangular matrix. See QR decomposition for a detailed description, computational algorithms, and applications.

See Input Data for the description of how to enter matrix or just click Example for a simple example.
