Transfer-matrix method
（重定向自Transfer matrix method）
In physics and mathematics, the transfer-matrix method is a general technique for solving problems in statistical mechanics.
The basic idea is to write the partition function in the form
where v0 and vN+1 are vectors of dimension p and the pxp matrices Wk are the so-called transfer matrices. In some cases, particularly for cyclic systems, the partition function may be written more simply as
