Subject: [Boost-commit] svn:boost r72742 - in sandbox/odeint/branches/karsten: boost/numeric/odeint/external/gsl boost/numeric/odeint/stepper boost/numeric/odeint/util libs/numeric/odeint/ideas/state_wrapper
From: mario.mulansky_at_[hidden]
Date: 2011-06-24 10:29:34
Author: mariomulansky
Date: 2011-06-24 10:29:32 EDT (Fri, 24 Jun 2011)
New Revision: 72742
URL: http://svn.boost.org/trac/boost/changeset/72742
Log:
deleted adjust_size_callers (default_adjust_size , matrix_vector_adjust_size), vector-matrix resizing is now implemented simply by respective specializations of same_size and adjust_size - see ublas_resize.hpp
Removed:
sandbox/odeint/branches/karsten/boost/numeric/odeint/util/default_adjust_size.hpp
sandbox/odeint/branches/karsten/boost/numeric/odeint/util/matrix_vector_adjust_size.hpp
sandbox/odeint/branches/karsten/boost/numeric/odeint/util/ublas_permutation_matrix_resize.hpp
