随后,此字符串将被传递给VectorSpace模块,并且数据散列的数据结构将依靠文件名来获得文件内的向量列表。
This string is then passed into the VectorSpace module, and a data hash data structure is keyed on the filename for the list of vectors within a file.
清单7中的for循环将它们奇怪的文件名转换成简单的X,Y(列和行)坐标,并将它们的值存储在%vals散列中。
The for loop in Listing 7 translates their filename vagaries into simple X, Y (column and row) coordinates, and stores their values in the % vals hash.
