I am experiencing the following error. Maybe someone can help. I am on a macOS Sierra version 10.12.4 and using Matlab 2017a.
>> syms x
Error using mupadmex
Error in MuPAD command:
Error in sym>cell2ref (line 1281)
S = mupadmex(y);
Error in sym>tomupad (line 1219)
S = cell2ref(numeric2cellstr(x));
Error in sym (line 179)
S.s = tomupad(x);
Error in syms (line 144)
toDefine = sym(zeros(1, 0));

Executing "which -all sym" reveals if there is a custom file with the same name "sym", which is causing this error. Renaming the custom file resolved the issue.

Thank you for your response. Unfortunately, that is not the cause of the problem. I get
>> which -all syms
/Volumes/MacintoshHD2/Software/MATLAB_R2017a.app/toolbox/symbolic/symbolic/syms.m
>> which -all sym
/Volumes/MacintoshHD2/Software/MATLAB_R2017a.app/toolbox/symbolic/symbolic/@sym/sym.m % sym constructor

You have an installation problem of some sort.
What shows up for
!otool -L /Volumes/MacintoshHD2/Software/MATLAB_R2017a.app/toolbox/symbolic/symbolic/mupadmex.mexmaci64
?
