Abstract: Based on the Guass-Seidel progressive iterative approximation for least squares fitting( LSPLA) algorithm , a Succesive Over Relaxation LSPIA ( SOR-LSPIA ) algorithm is proposed in this paper. We analysis the convergence of this. Furthermore some numerical is tests experiments are shown, our aIgorithm has fewer number iteration steps and shorter cpu time than the GS-LSPIA algorithm does if the fitting accracies are requared the same.#@#@#摘要: 本文以Guass-Seidel progressive iterative approximation for least squares fitting( LSPLA)算法...
