URL: <http://savannah.gnu.org/bugs/?53205> Summary: buttord function MATLAB compatibility issue Project: GNU Octave Submitted by: botondkirei Submitted on: Thu 22 Feb 2018 01:17:16 PM UTC Category: Octave Function Severity: 3 - Normal Priority: 5 - Normal Item Group: Matlab Compatibility Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: 4.2.1 Operating System: Any _______________________________________________________ Details: The MATALB function "buttord" is suitable to obtain the order of an analogic filter too. The common use for analog filter design is "buttord(...,'s')" - the 's' flag is appended in the argument list. The current versions of Siganl package of OCTAVE is not compliant with the MATLAB function. Proposed solution: I am not sure how to contribute to octave's signal package codebase, thus I created a development branch: https://sourceforge.net/u/botondkirei/octave/ci/default/tree/ The proposed implementation is in the branches buttord.m function. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?53205> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
