                 TDsolve(c, d, e, b)
              or TDsolve(c, d, e, b, which=which)

         returns the solution to the tridiagonal system:
            D(1)*x(1)       + E(1)*x(2)                       = B(1)
    	C(1:-1)*x(1:-2) + D(2:-1)*x(2:-1) + E(2:0)*x(3:0) = B(2:-1)
    	                  C(0)*x(-1)      + D(0)*x(0)     = B(0)
         (i.e.- C is the subdiagonal, D the diagonal, and E the superdiagonal;
         C and E have one fewer element than D, which is the same length as
         both B and x)
         B may have additional dimensions, in which case the returned x
         will have the same additional dimensions.  The WHICH dimension of B,
         and of the returned x is the one of length n which participates
         in the matrix solve.  By default, WHICH=1, so that the equations
         being solved involve B(,..) and x(+,..).
         Non-positive WHICH counts from the final dimension (as for the
         sort and transpose functions), so that WHICH=0 involves B(..,)
         and x(..,+).
         The C, D, and E arguments may be either scalars or vectors; they
         will be broadcast as appropriate.
