As the use cases of scalar and block tridiagonal solvers differ significantly in most applications the implementation of the two libraries is separated in two subprojects in /scalar and /block directories. These subprojects can be built from corresponding directories using CMake. TEST APPLICATIONS ----------------- Test applications in /apps include: 1) the solution of the heat diffusion PDE using the ADI (Atlernating Direction Implicit) method and 2) the solution of a general block tridiagonal system of equations. BUILDING -------- Details on building the subprojects (solvers and test applications) can be found in the README file of the appropriate subdirectories..
