Hi,
I am using trial Matlab 2017a on my MacBook (Retina, 12-inch, Early 2016, OSX 10.12.5).
And I just found that the syms function cannot work. The command I input and returned information is as below: Trial>> syms x Error using mupadmex Error in MuPAD command:
Error in sym>cell2ref (line 1308) S = mupadmex(y);
Error in sym>tomupad (line 1246) S = cell2ref(numeric2cellstr(x));
Error in sym (line 199) S.s = tomupad(x);
Error in syms (line 192) toDefine = sym(zeros(1, 0));
Any solution for this problem? Thank you.

And I tried the commands: restoredefaultpath rehash toolboxcache
but they did not help.

I am also having the same problem. While stepping through the sym.m file, it seems that the string parameter x for tomupad() is actually an empty 1 by 0 cell which is causing the error later on since the mupadmex function requires a string input. I'm not sure if there's any clear way to fix this. My last ditch effort will be to reinstall matlab and hope the issue fixes itself. Can someone else please look into this?

Actually, don't do that. It hung my system. But found the solution too. Rename the libfreetype.so files in /MATLAB installation dir/bin/glnxa64 to whatever you like. I found this solution here: https://bugs.archlinux.org/task/57948 and https://forums.gentoo.org/viewtopic-t-1078610-start-0-postdays-0-postorder-asc-highlight-.html?sid=ab27c1ca8e1927691858595185e18284

I am on a Linux System (Manjaro Linux 17). Fixed the issue by downgrading the fontconfig package. I noticed an error message in the terminal that gave me the idea. Hope it helps you.
