发帖数: 2975 | 1 Suppose I have a n dimension lattice where the basis is V1,V2,V3,...,Vn
L = a1V1+a2V2+...+anVn
=[a1 a2 a3 ... an][v1 v2 ... vn]'
a1,...an are all integers
Now I define a new lattice
K = L+b0P0+b1P1+b2P2+b3P3
=[a1 a2 a3 ... an][v1 v2 ... vn]'+b0P0+b1P1+b2P2+b3P3
=[a1 a2 a3 ... an b0 b1 b2 b3][v1 v2 ... vn P0 P1 P2 P3]'
b0,b1,b2,b3 are in {0,1}
what's the basis for K?
Thanks a lot! | C********n

你都写成这个形式，你还问什么是基

because I am looking for a nxn matrix
