The code contained in this distribution was (unless otherwise noted, e.g. testing/ls_logsumexp.m) written by Iain Murray. Most files specify dates, and any other important details. For some people having a formal license seems important, so I have included a standard one below. Let me know if you need a different license and I'll probably agree. The GPL version 2 or 3 is definitely ok, although I'm pretty sure the license below would already allow using those. As most (all?) of these functions are small and really simple, I'm obviously not going to chase down their usage. Just make sure no blame comes my way! ----- Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, provided that the above copyright notice(s) and this permission notice appear in all copies of the Software and that both the above copyright notice(s) and this permission notice appear in supporting documentation.
