This is really old school, but a lot of times we have users sending us
copy pasting of codes, and that is the only way to know the version of
the code.
This is mostly a long term maintenance improvement.
Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.
By removing whitespace on one patch, it makes future
code reviews much easier.

Use \par instead of \details for section.
add a Contributors Section and a Reference Section.
Remove (some) verbatim section when not needed.
Those changes have been done by hand so I am not sure I manage to catch them all.
Patch was based on 3.3.0, so required a little bit of merging.
Thank you Sven for the corrections.

I made ALPHA and BETA REAL/DOUBLE and introduced COMPLEX/COMPLEX*16
CALPHA since calls to C/ZHFRK need real alpha and beta. In calls to

In cerrrfp.f, I replaced 1.0D0 with 1.0E0 (not strictly necessary, but
cleaner).

Problem in ?(sy/he)tri2 was found.
For matrices with small N subroutine pass parameter NBMAX to ?(sy/he)tri2x which could be large than N.
In test for this functionality this is hide. Local test subroutine ilaenv.f pass proper values of NB. But if use ordinary ilaenv we will get mistake.
If we implemented
IF ( NBMAX .GE. N ) THEN
MINSIZE = N
ELSE
MINSIZE = (N+NBMAX+1)*(NBMAX+3)
END IF
and will call
IF( NBMAX .GE. N ) THEN
CALL SSYTRI( UPLO, N, A, LDA, IPIV, WORK, INFO )
ELSE
CALL SSYTRI2X( UPLO, N, A, LDA, IPIV, WORK, NBMAX, INFO )
END IF
the problem will be solved.
Some other minor changes on workspace query.
Post from Alexander Kobotov (INTEL)
In LAPACK 3.3 ?(SY/HE)SV are updated to use TRS2.
The TRS2 requires WORK(N) to operate, whereas in SV requirements for LWORK just to be >=1.
There is no any check in SV if LWORK>=N, the array WORK just passed as it is to TRS2.
So if LWORK<N a crash could occur while executing TRS2 due to overuse of allocated workspace.
I guess for the case of LWORK<N just previsous Level2 based ?(SY/HE)TRS should be used.
Update the testing accordingly
[DSYTRI2] Comit dsytri2 to get some feedback
Update the testing accordingly
DSYTRI2 is the Level 3 blas Version of DSYTRI
The actual routine that does the work is DSYTRI2X (name can be changed)
DSYTRI2 is just a wrapper to allow to hide the 2D Workspace required by the routine.
The interface had to be changed to integrate the possibility of doing a workspace query.
DSYTRI2x implementation will be documented in a LAWN. This algorithm was inspired by the following paper:
"Families of Algorithms Related to the Inversion of a Symmetric Positive Definite Matrix"
PAOLO BIENTINESI Duke University and BRIAN GUNTER Delft University of Technology and ROBERT A. VAN DE GEIJN The University of Texas at Austin
Add SYCONV routine: convert back and forth the factorization returned by SYTRF to be able to call SYTRS2.
Modify SYSV that now is calling SYTRS2 instead of SYTRS (and also SYCONV to convert and revert the factorization returned by SYTRF).
Modify testing to have TRS but also TRS2 tested in the LIN testing for SY.
