sposl
sposl - (obsolete) solve the linear system Ax = b for a symmetric positive definite matrix A,
which has been Cholesky-factored by SPOCO or SPOFA, and vectors b and x.

void sposl(float *a, int lda, int n, float *b);
void sposl_64(float *a, long lda, long n, float *b);
-
* A (input)
-
Cholesky factorization of the matrix A, as computed by SPOCO or SPOFA.
-
* LDA (input)
-
Leading dimension of the array A as specified in a dimension
or type statement. LDA >= max(1,N).
-
* N (input)
-
Order of the matrix A. N >= 0.
-
* B (input/output)
-
On entry, the right-hand side vector b.
On exit, the solution vector x.
