Out the main elements of cancellation is received by the Gaussian elimination method to improve the methods for solving linear equations, which is commonly used in computer solutions of low-density matrix equations of ways. Main-element elimination is the main element in every election, only the order of columns selected by the largest element in absolute value as the main element, and only the exchange of two lines, further elimination calculations. Program assigned by the matrix elements of the array, and then operating the array so as to achieve the purpose of dealing with matrices. This will be the matrix into upper triangular form, easily solved equations of the final group solution. Equations in the calculation of the final solution, the application of back substitution method to calculate all the solutions of equations.
