incidence 还可以表示某件事情的发生或发生的次数。例如：

作为动词时，matrix 表示将多个元素或变量组合成一个矩阵或数组。例如：

matrix 通常用于科学、工程和数学领域，在这些领域中，矩阵常用于描述和分析模型和关系。例如：

The matrix of genetic traits that contribute to a certain disease is very complex. (导致某种疾病的遗传特征的矩阵非常复杂。)
The matrix of equations we used to solve the problem was quite difficult. (我们用来解决这个问题的方程矩阵相当困难。)
