disablesignalslog.m

% function disablesignalslog(topmodelname,varargin)
%
% This function parses automatically
% all signals of the given modelname
% (comprising all submodels)
% and asks whether to disable log for
% signals (which are marked for logging)
%
% the function asks before removing any logging
% unless the additional parameter couple 'force', 1
% is given in varargin
%
% it seems that the Simulink Data Inspector
% is resilient to this changes
% try this:
% 1) Simulink.sdi.clear
% 2) restart Matlab
% 3) Delete signals manually there
