- DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
- On Entry
-
- NNNN INTEGER
- is the order of the tridiagonal matrix.
-
- DDDD DOUBLE PRECISION(N)
- is the diagonal of the tridiagonal matrix.
- On output D is destroyed.
-
- EEEE DOUBLE PRECISION(N)
- is the offdiagonal of the tridiagonal matrix.
- E(1) through E(N-1) should contain the
- offdiagonal.
-
- BBBB DOUBLE PRECISION(N)
- is the right hand side vector. On Return
-
- BBBB contains the solution. LINPACK. This version dated 08/14/78 . Jack
