Class Strtrs

    java.lang.Object
      org.netlib.lapack.Strtrs

    public class Strtrs

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.
    Contact seymour@cs.utk.edu with any questions.

     *     ..
     *
     *  Purpose
     *  =======
     *
     *  STRTRS solves a triangular system of the form
     *
     *     A * X = B  or  A**T * X = B,
     *
     *  where A is a triangular matrix of order N, and B is an N-by-NRHS
     *  matrix.  A check is made to verify that A is nonsingular.
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  A is upper triangular;
     *          = 'L':  A is lower triangular.
     *
     *  TRANS   (input) CHARACTER*1
     *          Specifies the form of the system of equations:
     *          = 'N':  A * X = B  (No transpose)
     *          = 'T':  A**T * X = B  (Transpose)
     *          = 'C':  A**H * X = B  (Conjugate transpose = Transpose)
     *
     *  DIAG    (input) CHARACTER*1
     *          = 'N':  A is non-unit triangular;
     *          = 'U':  A is unit triangular.
     *
     *  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.
     *
     *  A       (input) REAL array, 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.
     *
     *  LDA     (input) INTEGER
     *          The leading dimension of the array A.  LDA >= max(1,N).
     *
     *  B       (input/output) REAL array, dimension (LDB,NRHS)
     *          On entry, the right hand side matrix B.
     *          On exit, if INFO = 0, 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
     *          > 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.
