Abstract

PURPOSE:To execute the analysis having a practical evaluation accuracy in a short period in obtaining a simultaneous equation used for the analysis of a numeric calculation by providing a storage means storing a coefficient matrix or the like and an arithmetic means obtaining a solution of the simultaneous equation or the like in acquiring the simultaneous equation used for the analysis by the numerical calculation. CONSTITUTION:A control section 1 stores a coefficient matrix A registered in a file 8, a right side vector (b) and an error evaluation known solution vector (c) into a main storage device 2. Then an additional right side vector calculation section 5 is started and an additional right side vector b' (=Ac) is calculated by using the matrix A and the vector (c) stored in the device 2. Succeedingly, a simultaneous equation solution acquisition section 4 is started, the matrix A and the vector (b) are subjected to forward elimination processing, the matrix A is transformed into a triangle matrix and the vector (b) is also transformed. Then solutions x, y of simultaneous equations Ax=b and Ay=b' are generated through a solution acquisition section 4 and a solution acquisition addition section 6, and an error vector DELTAx is obtained through an error evaluation section 7 and displayed on a display device 9. Thus, the result of analysis having a practical evaluation accuracy is obtained in a short period.
