By default, all O2scl classes and functions which are not listed as being in one of O2scl 's smaller specialized namespaces are in this namespace. This namespace has been removed from the documentation to simplify the formatting.
For a full list of all the O2scl classes, see Data Structures. For a full list of all the O2scl global objects which are not classes, see Files::Globals.

Solve an asymmetric cyclic tridiagonal linear system.
solve following system w/o the corner elements and then use Sherman-Morrison formula to compensate for them
diag[0] abovediag[0] 0 ..... belowdiag[N-1] belowdiag[0] diag[1] abovediag[1] ..... 0 belowdiag[1] diag[2] 0 0 belowdiag[2] ..... ... ... abovediag[N-1] ...
