摘要
为了解决大型行列式计算中速度较慢的问题,采用多学科相结合的方法,对经典的列主元消去法进行探讨。通过将AVL理论进行拓展,将其应用到行列式计算中。在行列式列主元求解中,应用拓展的AVL理论,全面制定了行列式求解步骤和过程。与此同时,通过复杂度分析对基于拓展的AVL理论的行列式快速求解方法进行了定量分析,从而确定了改进方法的先进性、科学性和稳定性,为全面降低大型、超大型行列式运算复杂度提出了切实可行的明确的改善方法。
In order to solve large-scale, large-scale computing. The problem of low speed, using computer algorithms, al- gebra and other scientific methods combined, the classic main element elimination method are discussed. The AVL theo- ry development, which will be applied to computing. In the determinant of PCA solving, application of AVL theory, de- veloped a comprehensive determinant solution procedure and process. At the same time, through algorithm complexity analysis based on extended AVL theory of fast calculation method of quantitative analysis, thus determining the improve- ment method is advanced, scientific sex and stability, to reduce overall large, super large determinant computation com- plexity presents practical clear improvement method.
