version 2.2.1 -- 11/8/01
Alter the QR rotation routines supporting singular value
decomposition qrbdv.c, qrbdu1.c, and qrbdi.c to avoid a
rare numerical instability.
Modify the installation script makelibs.sh to ensure that
the new QR rotation code is not compiled with optimization.
The QR fix does not survive the GNU compiler's optimization.
Alter include in sany.c to read: #include "../ccmath.h".
version 2.2.0 -- 12/13/00
Convert all function definitions to the modern ASCII style.
Revise test programs to support automatic checking of their
output against the sample output appended as a comment to
the test code source. Modifications were made to most of
the test code to support this.
Supply shell code to permit the automatic checks of standard
test outputs.
Corect the manual entry for the values returned by the
solv function (revision in C-01).
version 2.1.2 -- 10/05/00
Modify installation scripts makelibs.sh and install.sh
to eliminate an undefined linker option.
Correct structure initializations in ccmath.h. (missing
braces)
Use <stdlib.h> to define all references to allocation
functions calloc() and malloc(). This header is now
included by ccmath.h.
Correct failures to free allocated storage in some eigenvalue
routines.
Change declarations of unsigned long to unsigned int
to correct problems on the DEC Alpha where unsigned long
has a length of 64 bits.
Revise ccmath.h and manual to reflect the altered
declarations of unsigned quantities. (Revisions in
C-07, C-10, and C-14.)
Fixed a bug in the singular value distribution code
that could lead to an attempt to operate with NANs.
version 2.1.1 -- 5/19/00
Revise hash storage programs to allow use of multiple
hash schemes in a program. ( Programs that use the
functions hashins, hashdel, hfind, and hval must be
revised to use this new form.)
Revised manual chapter C10-sort to reflect hash function
changes.
Minor correction in manual chapter C01-matrix.
Clean up anachronistic K&R type declarations of calloc
and malloc. (stdlib.h is now used)
Alter index incrementation code in time series functions
that resulted in warnings from DEC ALPHA compiler.
version 2.1.0 -- 5/1/00
Add section containing benchmark test code and output.
('benchmk' directory )
Specify use of '/bin/sh' in installation scripts
Change license policy to LPGL the GNU library public license.
version 2.0.1 -- 2/27/00
Correct spelling error in script 'install.sh'.
3/19/00
Correct function name in '~/simu/supp/lranb.c' : "lrana() -> lranb()".
