Fix upper case issue in CMakeLists reported by Julien Shueller on Nov 17th to Julie

configure_file(${CMAKE_CURRENT_SOURCE_DIR}/CMAKE/cblas-config-build.cmake.in

Commit fix proposed by Julien Schueller
Sent to LAPACK mailing list on Nov 16th 2015
spotted a minor inconsistency in the lapacke cmake config files install directory location.
in CMakeLists.txt:
install(FILES
${LAPACK_BINARY_DIR}/CMakeFiles/lapack-config.cmake
${LAPACK_BINARY_DIR}/lapack-config-version.cmake
DESTINATION ${LIBRARY_DIR}/cmake/lapack-${LAPACK_VERSION}
)
in LAPACKE/CMakeLists.txt:
install(FILES
${CMAKE_CURRENT_BINARY_DIR}/CMakeFiles/lapacke-config.cmake
${LAPACK_BINARY_DIR}/lapacke-config-version.cmake
DESTINATION lib/cmake/lapacke-${LAPACK_VERSION}
)
So lapack-config.cmake and lapacke-config-version.cmake could be installed in different directories in cases where CMAKE_INSTALL_LIBDIR is not set to "lib", eg Fedora or RHEL.
I propose to fix LAPACKE/CMakeLists.txt:
sed -i "s|DESTINATION lib/cmake/lapacke|DESTINATION \${LIBRARY_DIR}/cmake/lapacke|g" LAPACKE/CMakeLists.txt

The subroutine DSYCONV stores the supdiagonal of the symmetric 1-by-1 or 2-by-2
block matrix in the array WORK. (Or the subdiagonal, same array.) Before

assumed to be zero in subsequent subroutines. This is fine, but I think a
better behavior for the subroutine is to initialize these zero entries to zero.
So the commit is initializing these entries to zero.

0.

Since the goal of xLASET is to set values in A, we consider it OK if A contains NaN in input.

(So we do check for NaN in alpha and in beta and return error if NaN.)

Commit bug reported by Alexander Kobotov (INTEL) on LAPACK Forum

Recent commit r1533 introduced out of bound access which could lead to a crash.
It results scaling of a vector instead of a single number.
Fix is simple:
zhgeqz.f:669
- CALL ZSCAL( ILAST, SIGNBC, H( ILAST, ILAST ), 1 )
+ CALL ZSCAL( 1, SIGNBC, H( ILAST, ILAST ), 1 )
Similar for chgeqz on line 668

Fix [CDSZ]QRT17.
This is a routine to test DGELS which solves solves full rank overdetermined ( linear least squares ) or underdetermined (minimum norm) linear systems.
The check is, as follows,
(1) If the system is consistent, (smallresidual,) we check that
|| A^T ( b – A * x ) || / (||A||*||b||*max(M,N,NRHS)*eps)
is small (say less than 30).
(2) If the system is not consistent, (large residual,) we check that
|| A^T ( b – A * x ) || / (||A||*|| b - A*x ||*max(M,N,NRHS)*eps)
is small (say less than 30).
DQRT17 was checking in the not consistent case (large residual) that
|| A^T ( b – A * x ) || / (||A||*||x||*max(M,N,NRHS)*eps)
is small. It is a mistake and we need to change the ||x|| by a ||r||.
This fix is consistent with what the documentation says and makes more sense.

These are two fixes in [S,C,D,Z]-LAGGE.
(1) The routine was writing ZEROs out of bound in some specific cases. This is
corrected. Thanks to Yi Meng (CU Denver) for finding the bug.
(2) Quick exit when KL=KU=0 in this case, the user wants a diagonal matrix,
there is probably no reason to call this routine if one simply wants a diagonal
matrix, but that said we still ought to return a correct answer. A quick exit
makes the trick. The routine was not working otherwise.

This partially fixes bug 061 reported by Victor Liu.
Some compilers allocate local arrays on the heap when their size is
above a particular threshold.
This leads to wrong results when multiple threads call the same routine.
The bug fix consists in using a larger workspace, as proposed by Victor Liu
(Tue Nov 13, 2012).
Some routines still have large local arrays and cannot be fixed that way
because they have no workspace parameter: xGBTRF, xBPTRF, and xHSEQR.
