Public API class for QR decomposition QR decomposition decomposes any matrix A such that: A = Q.R Where: Q is an orthogonal matrix R is an upper triangular matrix

Method Summary

Modifier and Type	Method and Description
static IQRResult	decompose(AMatrix matrix) Computes the QR factorisation of a matrix A such that: A = Q.R Where: Q is an orthogonal matrix R is an upper triangular matrix If A is rectangular (m x n where m>n) then Q will also be (m x n)
static IQRResult	decompose(AMatrix matrix, boolean compact) Computes the QR factorisation of a matrix A such that: A = Q.R Where: Q is an orthogonal matrix R is an upper triangular matrix If A is rectangular (m x n where m>n) then Q will also be (m x n)
static IQRResult	decomposeCompact(AMatrix matrix) Computes the QR factorisation of a matrix A such that: A = Q.R Where: Q is an orthogonal matrix R is an upper triangular matrix If A is rectangular (m x n where m>n) then Q will also be (m x n)
