SIMULTANEOUS LINEAR EQUATION ANALYZING SYSTEM AND DEVICE

PURPOSE:To produce a general-purpose program in order to solve a simultaneous linear equation without considering any method used for a matrix solution by distributing automatically the matrix solution after deciding the symmetricalness and the diagonal priority of the matrix. CONSTITUTION:A simultaneous linear equation 102 is obtained by making a partial differential equation discrete that controls the physical phenomena like the flow of water or air, etc., by such numerical simulation methods like a finite element method, a differential method, etc. Then a symmetricalness deciding part 103 decides whether the matrices of the equation 102 are symmetrical to each other or not by using the equation 102 as the input information. In regard to the matrices which are decided as the symmetrical and diagonal prior matrices by the part 103 and a diagonal priority deciding part 104, a matrix symmetricalness processing part 105 applies the processing to those matrices to get rid of the effect of the boundary conditions of the first kind. If the parts 103 and 104 decide the asymmetrical and non-diagonal prior matrices, the equation 102 is solved by a matrix solution 106 in regard to these matrices.
