Class Spptrs

    java.lang.Object
      org.netlib.lapack.Spptrs

    public class Spptrs

extends java.lang.Object

    Following is the description from the original
    Fortran source.  For each array argument, the Java
    version will include an integer offset parameter, so
    the arguments may not match the description exactly.

     *  Purpose
     *  =======
     *
     *  SPPTRS solves a system of linear equations A*X = B with a symmetric
     *  positive definite matrix A in packed storage using the Cholesky
     *  factorization A = U**T*U or A = L*L**T computed by SPPTRF.
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  Upper triangle of A is stored;
     *          = 'L':  Lower triangle of A is stored.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.
     *
     *  NRHS    (input) INTEGER
     *          The number of right hand sides, i.e., the number of columns
     *          of the matrix B.  NRHS >= 0.
     *
     *  AP      (input) REAL array, dimension (N*(N+1)/2)
     *          The triangular factor U or L from the Cholesky factorization

     *          A = U**T*U or A = L*L**T, packed columnwise in a linear
     *          array.  The j-th column of U or L is stored in the array AP
     *          as follows:
     *          if UPLO = 'U', AP(i + (j-1)*j/2) = U(i,j) for 1<=i<=j;
     *          if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = L(i,j) for j<=i<=n.
     *
     *  B       (input/output) REAL array, dimension (LDB,NRHS)
     *          On entry, the right hand side matrix B.
     *          On exit, the solution matrix X.
     *
     *  LDB     (input) INTEGER
     *          The leading dimension of the array B.  LDB >= max(1,N).
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit
     *          < 0:  if INFO = -i, the i-th argument had an illegal value
     *
     *  =====================================================================
