From 3f0510629e422e979b57d3f93791937912a4183a 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version 1.5 is rather substantial, and introduces some minor backward-incompatibilities: * The header "#!symbols" has been replaced by "#!virtual_fields" * Multiplying polynomials using the '*' symbol is no longer supported (or, rather, the symbolic capabilities of meankondo were enhanced, and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 * 'meantools exp' has been removed (its functionality is now handled by other means) * 'meantoolds derive' has been replaced by 'meantools differentiate' * The symbolic capabilities were enhanced: polynomials can now be multiplied, added, exponentiated, and their logarithms can be taken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. * Created vim files to implement syntax highlighting for configuration files. * Multiple bug fixes --- man/kondo_preprocess.1 | 35 +++++++++++++++++++---------------- 1 file changed, 19 insertions(+), 16 deletions(-) (limited to 'man/kondo_preprocess.1') diff --git a/man/kondo_preprocess.1 b/man/kondo_preprocess.1 index 1e22cae..414a44a 100644 --- a/man/kondo_preprocess.1 +++ b/man/kondo_preprocess.1 @@ -1,5 +1,5 @@ -.Dd $Mdocdate: September 22 2015 $ -.Dt kondo_preprocess 1.4 +.Dd $Mdocdate: February 3 2016 $ +.Dt kondo_preprocess 1.5 .Os .Sh NAME .Nm kondo_preprocess @@ -13,11 +13,21 @@ for the Kondo model .Pp .Nm .Fl v +.Sh DEPRECATION NOTICE +The use of +.Nm +is deprecated as of +.Sy meankondo +v1.5. +.Pp +Similar functionality can be obtained rather easily using the enhanced symbolic capabilities introduced in v1.5, which are more flexible than +.Nm . +.Pp .Sh DESCRIPTION .Nm generates a configuration file to be read by .Sy meankondo -for the Kondo model.
