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
     *  =======
     *
     *  STRSYL solves the real Sylvester matrix equation:
     *
     *     op(A)*X + X*op(B) = scale*C or
     *     op(A)*X - X*op(B) = scale*C,
     *
     *  where op(A) = A or A**T, and  A and B are both upper quasi-
     *  triangular. A is M-by-M and B is N-by-N; the right hand side C and
     *  the solution X are M-by-N; and scale is an output scale factor, set
     *  <= 1 to avoid overflow in X.
     *
     *  A and B must be in Schur canonical form (as returned by SHSEQR), that
     *  is, block upper triangular with 1-by-1 and 2-by-2 diagonal blocks;
     *  each 2-by-2 diagonal block has its diagonal elements equal and its
     *  off-diagonal elements of opposite sign.
     *
     *  Arguments
     *  =========
     *
     *  TRANA   (input) CHARACTER*1
     *          Specifies the option op(A):
     *          = 'N': op(A) = A    (No transpose)
     *          = 'T': op(A) = A**T (Transpose)
     *          = 'C': op(A) = A**H (Conjugate transpose = Transpose)
     *
     *  TRANB   (input) CHARACTER*1
     *          Specifies the option op(B):
     *          = 'N': op(B) = B    (No transpose)
     *          = 'T': op(B) = B**T (Transpose)
     *          = 'C': op(B) = B**H (Conjugate transpose = Transpose)
     *
     *  ISGN    (input) INTEGER
     *          Specifies the sign in the equation:
     *          = +1: solve op(A)*X + X*op(B) = scale*C
     *          = -1: solve op(A)*X - X*op(B) = scale*C
     *
     *  M       (input) INTEGER
     *          The order of the matrix A, and the number of rows in the
     *          matrices X and C. M >= 0.
     *
     *  N       (input) INTEGER
     *          The order of the matrix B, and the number of columns in the
     *          matrices X and C. N >= 0.
     *
     *  A       (input) REAL array, dimension (LDA,M)
     *          The upper quasi-triangular matrix A, in Schur canonical form.
     *
     *  LDA     (input) INTEGER
     *          The leading dimension of the array A. LDA >= max(1,M).
     *
     *  B       (input) REAL array, dimension (LDB,N)
     *          The upper quasi-triangular matrix B, in Schur canonical form.
     *
     *  LDB     (input) INTEGER
     *          The leading dimension of the array B. LDB >= max(1,N).
     *
     *  C       (input/output) REAL array, dimension (LDC,N)
     *          On entry, the M-by-N right hand side matrix C.
     *          On exit, C is overwritten by the solution matrix X.
     *
     *  LDC     (input) INTEGER
     *          The leading dimension of the array C. LDC >= max(1,M)
     *
     *  SCALE   (output) REAL
     *          The scale factor, scale, set <= 1 to avoid overflow in X.
     *
     *  INFO    (output) INTEGER
     *          = 0: successful exit
     *          < 0: if INFO = -i, the i-th argument had an illegal value
     *          = 1: A and B have common or very close eigenvalues; perturbed
     *               values were used to solve the equation (but the matrices
     *               A and B are unchanged).
     *
