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.
-
* UPLO (input)
-
-
* N (input)
-
The order of the matrix A. N >= 0.
-
* A (input/output)
-
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 (input)
-
The leading dimension of the array A. LDA >= max(1,N).
-
* INFO (output)
