PROBLEM TO BE SOLVED: To solve a simultaneous linear equation in which whether or not a coefficient matrix is regular is not clear. SOLUTION: When calculation processing for solving a simultaneous linear equation is diffused by a conjugate gradient method (S107), an initial value is to be X<SB>MIN</SB>, and calculation processing for solving the simultaneous linear equation with the conjugate gradient method is operated (S108).
