algorithm and software implementation of qr decomposition of rectangular matrices
The QR decomposition in linear algebra calculation is widely applied. Despite that the algorithms for the decomposition are available, it lacks explanations how to implement them for non-square matrices. The research gives descriptions about the modifications, needed to apply for rectangular form of matrices. A software implementation of the algorithm is presented. It can be used for client or server side programming tools, performing linear algebra calculations and optimization.
