摘要
在数学中及工程技术中 ,对有关极值问题的讨论是一个非常重要的课题。对于这些问题的讨论有时可化为一些等式或一些行列式的计算。对一类极值问题进行了认真讨论和分析 ,给出了一类行列式的计算 ,并推广了阶乘的概念 ,且得到一类正定矩阵。
The study of extremums is a very important subject in math and engineering.The extremum calculation can be done by means of calculating certain equation or determinants.The analysis of extremums has been done to give the calculation of a series of determinants,and the concept of factorial has been advanced.As a result,a kind of positively definite matrix is achieved.
