NNNNAAAAMMMMEEEE
CPTSL - CPTSL given a positive definite tridiagonal matrix and a right
hand side will find the solution.
SSSSYYYYNNNNOOOOPPPPSSSSYYYYSSSS
SUBROUTINE CPTSL(N,D,E,B)
DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
On Entry
NNNN INTEGER
is the order of the tridiagonal matrix.
DDDD COMPLEX(N)
is the diagonal of the tridiagonal matrix.
On output D is destroyed.
EEEE COMPLEX(N)
is the offdiagonal of the tridiagonal matrix.
E(1) through E(N-1) should contain the
offdiagonal.
BBBB COMPLEX(N)
is the right hand side vector. On Return
BBBB contains the solution. LINPACK. This version dated 08/14/78 . Jack
