虽然二维数组与线性代数中的矩阵类似，但是对它们的操作(比如乘)与线性代数中的操作(比如矩阵乘)是完全不同的。

Even though two-dimensional arrays are similar to matrices from linear algebra, operations (such as multiply) have nothing to do with the operations in linear algebra (such as matrix multiplication).

此外，您可以使用该操作来迭代数组(包括基本类型数组)中的元素。

In addition, you can use this action to iterate through the elements of an array, including arrays of primitives.

然后，一个while循环迭代数据集，在一个方便的数组中存储信息以便将来进行显示。

A while loop then iterates through the dataset, storing the information in a convenient array for later display.
