From 167980ea437881ec56186332370afcc169f2e4dd Mon Sep 17 00:00:00 2001 From: Ian Jauslin Date: Tue, 14 Jun 2022 09:26:07 +0200 Subject: Update to v1.5. The update to version 1.5 is rather substantial, and introduces some minor backward-incompatibilities: * The header "#!symbols" has been replaced by "#!virtual_fields" * Multiplying polynomials using the '*' symbol is no longer supported (or, rather, the symbolic capabilities of meankondo were enhanced, and the syntax has been changed). * 'meantools exp' has been removed (its functionality is now handled by other means) * 'meantoolds derive' has been replaced by 'meantools differentiate' * The symbolic capabilities were enhanced: polynomials can now be multiplied, added, exponentiated, and their logarithms can be taken directly in the configuration file. * The flow equation can now be processed after being computed using the various "#!postprocess_*" entries. * Deprecated kondo_preprocess. * Compute the mean using an LU decomposition if possible. * More detailed checks for syntax errors in configuration file. * Check that different '#!group' entries are indeed uncorrelated. * New flags in meankondo: '-p' and '-A'. * New tool: meantools expand. * Improve conversion to LaTeX using meantools-convert * Assign terms randomly to different threads. * Multiple bug fixes --- src/coefficient.h | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'src/coefficient.h') diff --git a/src/coefficient.h b/src/coefficient.h index 43dd313..f8a813a 100644 --- a/src/coefficient.h +++ b/src/coefficient.h @@ -1,5 +1,5 @@ /* -Copyright 2015 Ian Jauslin +Copyright 2015-2022 Ian Jauslin Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License. @@ -48,12 +48,20 @@ int coefficient_concat_noinit(Coefficient input, Coefficient* output); // simplify a Coefficient int coefficient_simplify(Coefficient* coefficient); + +// put all terms under a common denominator and simplify the resulting fraction +int coefficient_simplify_rational(Coefficient constant, Coefficient* coefficient); +// put all terms under a common denominator +int coefficient_common_denominator(Coefficient constant, Coefficient* coefficient); +// simplify coefficient / constant +int coefficient_simplify_fraction(Coefficient constant, Coefficient coefficient, Coefficient* remainder, Coefficient* out); + // sort the terms in an equation (quicksort algorithm) int sort_coefficient(Coefficient* coefficient, int begin, int end); // exchange two terms (for the sorting algorithm) int exchange_coefficient_terms(int i, int j, Coefficient* coefficient); -// derive a coefficient with respect to an index (as a polynomial) (does not derive the 1/(1+C)^p ) +// differentiate a coefficient with respect to an index (as a polynomial) (does not differentiate the 1/(1+C)^p ) int coefficient_deriv_noinit(Coefficient input, int index, Coefficient* output); int coefficient_deriv(Coefficient input, int index, Coefficient* output); -- cgit v1.2.3-70-g09d2
