[英]How do I change the representation while storing a sparse matrix in python?
The sparse matrix representation is of the form: 稀疏矩阵表示形式为:
(i,j) value
I want to store these values to a text file in 3 columns namely: 我想将这些值存储到3列的文本文件中:
i j value
If your sparse matrix is stored in a dictionary called dict then you can use: 如果您的稀疏矩阵存储在字典dict中,则可以使用:
f = open('output.txt', 'w')
for (i, j), value in dict.items():
f.write("%s\t%s\t%s\n" % (i, j, value))
This will output the data as a tab-delimited text file. 这会将数据输出为制表符分隔的文本文件。
