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version 1.5 is rather substantial, and introduces some minor backward-incompatibilities: * The header "#!symbols" has been replaced by "#!virtual_fields" * Multiplying polynomials using the '*' symbol is no longer supported (or, rather, the symbolic capabilities of meankondo were enhanced, and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 * 'meantools exp' has been removed (its functionality is now handled by other means) * 'meantoolds derive' has been replaced by 'meantools differentiate' * The symbolic capabilities were enhanced: polynomials can now be multiplied, added, exponentiated, and their logarithms can be taken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/determinant.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 src/determinant.h (limited to 'src/determinant.h') diff --git a/src/determinant.h b/src/determinant.h new file mode 100644 index 0000000..613be87 --- /dev/null +++ b/src/determinant.h @@ -0,0 +1,17 @@ +/* + Compute the determinant of a number matrix +*/ + +#ifndef DETERMINANT_H +#define DETERMINANT_H + +#include "types.h" + +// determinant of a matrix +int determinant_inplace(Number_Matrix M, Number* out); + +// LU decomposition +int LU_dcmp_inplace(Number_Matrix M, int* sign_correction); + + +#endif -- cgit v1.2.3-70-g09d2
