Abstract :The coefficient matrix of a very large system of equations is generally very sparse, i. e., non-zero elements are very few, say, less than 10 percent of total number of elements. Thus in computer assisted analysis of such a system, sparsity oriental techniques for solution and data storage are very important. Recently, many papers have been published on the sparse matrix techniques. In this paper, three algorithms of so cal1ed "minimum fill-in" have been studied and actually programmed for FACOM 230-15 computer. Comparisions are made from the results of actual computations.
