NAME
     CPOSL   - CPOSL solves the COMPLEX Hermitian positive definite system A *
     X = B using the factors computed by CPOCO or CPOFA.

SYNOPSYS
      SUBROUTINE CPOSL(A,LDA,N,B)

DESCRIPTION
     On Entry

     A COMPLEX(LDA, N)
	the output from CPOCO or CPOFA.

     LDA INTEGER
	the leading dimension of the array  A .

     N INTEGER
	the order of the matrix	 A .

     B COMPLEX(N)
	the right hand side vector.  On Return

     B the solution vector  X . Error Condition

     A division by zero will occur if the input factor contains a zero on the
     diagonal.	Technically this indicates singularity but it is usually
     caused by improper subroutine arguments.  It will not occur if the
     subroutines are called correctly and  INFO .EQ. 0 .  To compute
     INVERSE(A) * C  where  C  is a matrix with	 P  columns
	CALL CPOCO(A,LDA,N,RCOND,Z,INFO)
	IF (RCOND is too small .OR. INFO .NE. 0) GO TO ...
	DO 10 J = 1, P
	CALL CPOSL(A,LDA,N,C(1,J)) 10 CONTINUE LINPACK.	 This version dated
