*
-* UPLO - CHARACTER*1.
-* On entry, UPLO specifies whether the matrix is an upper or
-* lower triangular matrix as follows:
-*
-* UPLO = 'U' or 'u' A is an upper triangular matrix.
-*
-* UPLO = 'L' or 'l' A is a lower triangular matrix.
-*
-* Unchanged on exit.
-*
-* TRANS - CHARACTER*1.
-* On entry, TRANS specifies the operation to be performed as

-*
-* TRANS = 'N' or 'n' x := A*x.
-*
-* TRANS = 'T' or 't' x := A**T*x.
-*
-* TRANS = 'C' or 'c' x := A**T*x.
-*
-* Unchanged on exit.
-*
-* DIAG - CHARACTER*1.
-* On entry, DIAG specifies whether or not A is unit
-* triangular as follows:
-*
-* DIAG = 'U' or 'u' A is assumed to be unit triangular.
