NAME    [Toc]    [Back]

     SSISL   - SSISL solves the	real symmetric system A	* X = B	using the
     factors computed by SSIFA.

SYNOPSYS    [Toc]    [Back]

      SUBROUTINE SSISL(A,LDA,N,KPVT,B)

DESCRIPTION    [Toc]    [Back]

     On	Entry

     A REAL(LDA,N)
	the output from	SSIFA.

     LDA INTEGER
	the leading dimension of the array  A .

     N INTEGER
	the order of the matrix	 A .

     KPVT INTEGER(N)
	the pivot vector from SSIFA.

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

     B the solution vector  X .	Error Condition

     A division	by zero	may occur if  SSICO  has set RCOND .EQ.	0.0 or	SSIFA
     has set INFO .NE. 0  .  To	compute	 INVERSE(A) * C	 where	C  is a	matrix
     with  P  columns
	CALL SSIFA(A,LDA,N,KPVT,INFO)
	IF (INFO .NE. 0) GO TO ...
	DO 10 J	= 1, P
	CALL SSISL(A,LDA,N,KPVT,C(1,J))	10 CONTINUE LINPACK.  This version
