NAME
       spotri.f -

SYNOPSIS
   Functions/Subroutines
       subroutine spotri (UPLO, N, A, LDA, INFO)
	   SPOTRI

Function/Subroutine Documentation
   subroutine spotri (characterUPLO, integerN, real, dimension( lda, * )A, integerLDA, integerINFO)
       SPOTRI

       Purpose:

	    SPOTRI computes the inverse of a real symmetric positive definite
	    matrix A using the Cholesky factorization A = U**T*U or A = L*L**T
	    computed by SPOTRF.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     = 'U':  Upper triangle of A is stored;
		     = 'L':  Lower triangle of A is stored.

	   N

		     N is INTEGER
		     The order of the matrix A.  N >= 0.

	   A

		     A is REAL array, dimension (LDA,N)
		     On entry, the triangular factor U or L from the Cholesky
		     factorization A = U**T*U or A = L*L**T, as computed by
		     SPOTRF.
		     On exit, the upper or lower triangle of the (symmetric)
		     inverse of A, overwriting the input factor U or L.

	   LDA

		     LDA is INTEGER
		     The leading dimension of the array A.  LDA >= max(1,N).

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
		     > 0:  if INFO = i, the (i,i) element of the factor U or L is
			   zero, and the inverse could not be computed.
