根据《数据结构》学所内容，使用C++中的封装、继承、运算符重载、类模板等技术，完成以上各个数据结构类的设计。-According to the data structure of the study content, use the inheritance, sealing, in c++ operator overloaded, class template technology, complete the above all data structure kind design.

subtraction, the zero members all change the, again call operation addition.

Multiplication, in can under the condition of multiples respectively, the each line processing: a column such as: if M in the first line of the first and last a nonzero, the first and the last, and N respectively in the first line and the last line of non-zero member multiplication. The results obtained by the position of the corresponding kept in, to deal with to the downside. The results in the same position on adding together. Finally with sparse matrix
