Abstract
A unified method to permute vector-stored Upper-triangular-Diagonal factorized covariance (UD) and vector-stored upper-triangular Square-Root Information (SRI) arrays is presented. The method involves cyclic permutation of the rows and columns of the arrays and retriangularization with fast (slow) Givens rotations (reflections). Minimal computation ts performed, and a one-dimensional scratch array is required. To make the method efficient for large arrays on a virtual memory machine, computations are arranged sO as to avoid expensive paging faults. This method is potentially important for processing large volumes of radio metric data in the DSN.
