This research is concerned with the development of a mathematical base that can be utilized to model data base management systems from the user level down to the bit level and to develop and evaluate proposed hardware that could be utilized to implement a data dictionary and part of a data directory. The mathematical modeling development is accomplished through set theory and the addition of order to sets. This mathematical ...
The algorithm reported here is implemented on the RADC STARAN and then used to invert test matrices. Matrices of dimensions 30 x 30, 45 x 45, 60 x 60 and 80 x 80 are inverted and these results are timed. The same matrices were inverted using APL Plus. In the cases of the 30 x 30 and 45 x 45 matrices, a direct comparison was made; this comparison indicates a ...
This report is a follow on to AD-A009 643, 'Timing Figures for Inverting Large Matrices Using the STARAN Associative Processor.' In that report timing equations were developed for matrices consisting of real numbers whereas this report deals with complex numbers. Algorithms and timing equations are developed for matrices of rank up to 511 and matrices with 512 < rank < 1023. Results indicate that it takes 2 1/2 to 4 ...
