Does boost provi开发者_运维技巧de any classes to implement a tridiagonal matrix?

Besides this, you are probably looking for a matrix where the 3 diagonal are contiguous. This is provided by a row-major banded matrix, since diagonals are mapped to rows and in row_major these are contiguous. The 3 diagonals are provided with one allocation and proper pointers can be easily obtained by &m(0,0), &m(1,0), &m(0,1)
