Parameters

storedTriangle  MatrixTriangle

            Specifies whether the details of the factorization are stored
            as an upper or lower triangular matrix.
            = 'U':  Upper triangular, form is A = U*D*UT;
            = 'L':  Lower triangular, form is A = L*D*LT.
            

n  Int32

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

nrhs  Int32

            The number of right hand sides, i.e., the number of columns
            of the matrix B.  NRHS >= 0.
            

a  Array2D<Double>

            Dimension (LDA,N)
            The block diagonal matrix D and the multipliers used to
            obtain the factor U or L as computed by DSYTRF.
            

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

ipiv  Array1D<Int32>

            Dimension (N)
            Details of the interchanges and the block structure of D
            as determined by DSYTRF.
            

b  Array2D<Double>

            Dimension (LDB,NRHS)
            On entry, the right hand side matrix B.
            On exit, the solution matrix X.
            

            The leading dimension of the array B.  LDB >= max(1,N).
            

info  Int32

            = 0:  successful exit
            < 0:  if INFO = -i, the i-th argument had an illegal value
            

This method corresponds to the LAPACK routine DSYTRS.
