Parameters

storedTriangle

Type: Extreme.MathematicsMatrixTriangle

            = 'U':  A is upper triangular;
            = 'L':  A is lower triangular.
            

trans

Type: Extreme.MathematicsTransposeOperation

            Specifies the form of the system of equations:
            = 'N':  A * X = B  (No transpose)
            = 'T':  AT * X = B  (Transpose)
            = 'C':  AH * X = B  (Conjugate transpose = Transpose)
            

diag

Type: Extreme.MathematicsMatrixDiagonal

            = 'N':  A is non-unit triangular;
            = 'U':  A is unit triangular.
            

n

Type: SystemInt32

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

nrhs

Type: SystemInt32

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

a

Type: Extreme.CollectionsArray2DT

            Dimension (LDA,N)
            The triangular matrix A.  If UPLO = 'U', the leading N-by-N
            upper triangular part of the array A contains the upper
            triangular matrix, and the strictly lower triangular part of
            A is not referenced.  If UPLO = 'L', the leading N-by-N lower
            triangular part of the array A contains the lower triangular
            matrix, and the strictly upper triangular part of A is not
            referenced.  If DIAG = 'U', the diagonal elements of A are
            also not referenced and are assumed to be 1.
            

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

b

Type: Extreme.CollectionsArray2DT

            Dimension (LDB,NRHS)
            On entry, the right hand side matrix B.
            On exit, if info = 0, the solution matrix X.
            

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

info

Type: SystemInt32

info is INTEGER
            = 0:  successful exit
            < 0: if info = -i, the i-th argument had an illegal value
            > 0: if info = i, the i-th diagonal element of A is zero,
                 indicating that the matrix is singular and the solutions
                 X have not been computed.
            

            A check is made to verify that A is nonsingular.
            

This method corresponds to the LAPACK routine DTRTRS.
