Angelika Schwarz a8028e9ddc Fix undefined reference to cblas_[sd]cabs1 
cblas.h defines

   double cblas_dcabs1(const void  *z);
   float  cblas_scabs1(const void  *c);

but does not provide an implementation. This commit adds
the missing implementation in the common CBLAS style and
eliminates the linker error when calling the above function.

Angelika Schwarz 0a7dec1ff1 Avoid NaN generation in LATRS 
Fixes #714
 2022-09-25 17:38:34 +02:00
Angelika Schwarz 7ce9bf5fca Set SCALE early for robust triangular solvers 
1) The docs define SCALE as an output argument. Set SCALE *before*
the quick return case to have SCALE defined in all cases. This is
how the similar routine TRSYL handles the case already.

2) Remove invocations of LABAD in complex routines and be consistent
with their real counterparts, which do not call LABAD.

Angelika Schwarz 970a7721d8 Add BLAS-3 robust triangular solver T*X = B*diag(s1, ..., sN) 
An extensions of LATRS solving T*x = s*x to many right-hand sides,
allowing the usage of BLAS-3.

The new algorithm tends to use less aggressive scaling,
in particular for larger matrices.

Angelika Schwarz 079c185c6a Add ztrsyl3 and corresponding tests 
The tests of ztrsyl via zget35 are on tiny matrices that fall into the
unblocked section of ztrsyl3. Add a new test file that checks ztrsyl(3)
for larger matrices and their compatibility: Every problem that is
solvable by ztrsyl must be solvable by ztrsyl3.

Angelika Schwarz cda8a83b76 Add level-3 BLAS triangular Sylvester equation solver 
Force compatibility with [ds]trsyl. Use two floating-point
scaling factors (rather than integer scaling factors).
This does not eliminate the problem that scalings can be flushed,
making any result useless. That problem could be eliminated
by replacing the floating-point scale factor with an integer
scale factor.
