QR Decomposition

QR Decomposition is a fundamental technique in linear algebra that has wide applications in various fields of science and engineering. It involves decomposing a matrix into the product of two simpler matrices: a unitary matrix Q and an upper triangular matrix R. QR Decomposition provides valuable insights into the structure of a matrix and simplifies many matrix operations.

History and Development

QR Decomposition was first introduced by the mathematician John Todd in 1956. He developed the algorithm as a more efficient method for solving systems of linear equations. Since then, QR Decomposition has been extensively studied and refined, and various algorithms have been developed to perform the decomposition.
