glucat-0.13.0

2025-03-02: 0.13.0
GluCat 0.13.0 has improved configuration and testing.

• Unused local typedefs have been removed from the C++ code.

• The deprecated configuration option ./configure --with-eig=bindings has been removed.

• The ability to build PyClical without Cython has been deprecated and will be removed in future versions.

• The configuration option ./configure --with-qd has improved configuration tests.

• The ./configure script adds g++ compiler options to ensure that FMA is used consistently on hardware that implements AVX512 instructions.

• The pyclical/setup_ext.py and pyclical/setup_nocython.py scripts have been refactored.

• The Python demo code has been brought up to date.

• The installation script pyclical/demos/kubuntu-24-conda-install-mayavi.sh and the environment script pyclical/demos/kubuntu-24-mayavi-env.sh have been added to simplify the installation and running of the Mayavi-based plotting demos on Kubuntu 24.10.

glucat-0.10.1

2022-02-19: 0.10.1
Some GluCat configuration options have been deprecated.

The following configuration options are deprecated as of GluCat 0.10.1
and will be removed in future releases. See INSTALL for details.

  --enable-check-isnan    check for NaN values at various places in the code
  --with-stdlib[=ARG]     C++ standard library to use (libcxx|libstdcxx)
  --with-map[=ARG]        type of map to use (map|stdunordered)
  --with-dense-mat        use dense matrices
  --with-random[=ARG]     type of random number generator to use (std|gsl)
  --with-pool-alloc       use Boost Pool allocator

glucat-0.10.0

GluCat 0.10.0 introduces a change in the way that the headers are to be used. Instead of

#include "glucat/glucat.h"
#include "my_tuning.h"
#include "glucat/glucat_imp.h"

with my_tuning.h containing a definition of Tune_P, the tuning policy class, you are expected to use

#include "glucat/glucat.h"
#include "glucat/glucat_imp.h"
#include "my_tuning.h"

with my_tuning.h containing a definition of the tuning policy class that you are using as a template parameter.
See README for details.

Also:

• The ./configure script has been refactored.
• Successfully running ./configure --with-eig=binding requires a Fortran compiler.
• The Python scripts used to build the PyClical extension module now use setuptools rather than distutils.

glucat-0.9.0

GluCat has revised promotion, truncation and printing

GluCat 0.9.0 introduces some changes that improve usability of the results, but produce bit-for-bit different output when compared to previous versions.

• Promotion of Scalar_T now increases the number of floating point mantissa bits on all tested architectures, including ARM v8. Demotion is the reverse.
• The default limit for the truncated() member function is now std::numeric_limits<Scalar_T>::epsilon().
• The constructor from framed_multi<> to matrix_multi<> now uses the default truncation before the transform, and the constructor from matrix_multi<> to framed_multi<> uses the default truncation after the transform.
• The truncation of output via operator<<() now depends on ostream precision(). See test17 for examples.

Some GluCat classes now have new member functions.

• clifford_algebra<>, framed_multi<>, matrix_multi<>: isinf(), operator-=()`.
• index_set<> reference: operator==().

The function isinf() has also been added to matrix.h and matrix_imp.h.

GluCat header code is now modernized. Compilation now requires C++11.

What's Changed

• Modernize C++ header code by @penguian in #19
• Make headers more self-contained by @penguian in #21
• Make promotion monotonic: add glucat/promotion.h by @penguian in #23
• Fix clang-tidy bugprone issues by @penguian in #25
• Add multivector isinf to match isnan by @penguian in #27
• Add multivector isinf to match isnan -- final 3 commits by @penguian in #29
• Update branch to match updated master by @penguian in #30
• Make default truncation depend on scalar type by @penguian in #31
• Issue 32 use truncation in transforms and printing by @penguian in #33
• Issue 34 use range based for loops by @penguian in #35
• Update test results and documentation for version 0.9.0 by @penguian in #37
