> Matlab is missing the file “eml_assert_all_constant”.  It should be a built in function (part of the signals toolbox).  However, this function appears to have been removed at Matlab version 7.1 and above.  The new Matlab 2014a version of the butter.m function doesn’t actually call eml, which suggests that your matlab is actually calling an old version of the butter.m function.  In a quick google search, it appears that a bunch of people have this issue and it seens to have been caused by an upgrade of matlab from an older version which left some of the old files in the path.  You might also have two versions of matlab on your computer.    You can test this by typing “which butter.m” into matlab and it should say something like:
> 
>>> which butter
> /Applications/MATLAB_R2014b.app/toolbox/signal/signal/butter.m
> 
> If I am right, its calling the butter.m from an older matlab version and the above command will point to a file in the older matlab folder.  In that case, deleting the old version or removing it from the path using the path tool (type “pathtool” in matlab) should fix the issue.
