矩阵的理论与方法在农业科研中的几个应用

APPLICATION OF THEORY AND METHOD OF MATRIX ON AGRICULTURAL SCIENTIFIC RESEARCH

本文介绍了利用矩阵的正定性讨论函数ｙ＝ｆ（ｘ１，ｘ２，…，ｘｎ），（ｎ≥２）的极值；将连续分布函数离散化，构造Ｌｅｓｌｉｅ矩阵，对群体动物进行动态研究；利用状态转移矩阵对多维系统中多个变量的变化规律的研究；利用转移概率矩阵研究经济系统中市场占有率及虫害预测等问题。

The maximum and minimum of function y=f(x 1,x 1…,x n)(n≥2)were discussed by positive difinite of matrix;Leslie matrix was structured by discrete continuous distribution function and then animals population dynamics were studied;the changing rule of several variables in multidimensional system was researched by state transiton matrix;market sharing and insect forecasting in economic system were analysed by transition probability matrix.
