Recurrence solution of a block tridiagonal matrix equation with Neumann, Dirichlet, mixed or periodic boundary conditions
Description
Title of program: PERDIAG Catalogue Id: AARF_v1_0 Nature of problem A theorist may wish to solve the matrix equation AU = W, rapidly, where A is a block tridiagonal matrix. This type of matrix equation frequently arises in the solution of problems in one space dimension; in the soluion of boundary-value and many initial-value problems (because the time-dependent problem has been formulated implicitly), where it is necessary to solve n coupled, finite difference equations. The program is capable of dealing with Neumann, Dirichlet, mixed or periodic boundary condi ...
