After updating my mac to Yosemite, everytime I call the function clearvars (e.g.
clearvars x y;
or:
clearvars -except z
)I have the following error:
Error using strjoin (line 14) Expected input to be one of these types:
char
Instead its type was cell.
Error in clearvars>createPattern (line 188) pattern = sprintf('(%s)$', strjoin(variableArgs, '|'));
Error in clearvars (line 70) clearVarPat = createPattern(clearVarArgs, flags.regexpClear);
Any help to solve this issue?

Alberto - which version of MATLAB are you using? Also, in the command window, type
which strjoin -all
What is returned?

Your question solved the problem. I had creepy strjoin.m in the path.
Many Thanks!!

Alberto ran the command
which strjoin -all
and noticed that he had a "creepy" strjoin.m file in the path.

>> which -all strjoin C:\Program Files\MATLAB\R2018a\toolbox\matlab\strfun\strjoin.m
if there are any other strjoin.m then go to setpath in matlab and copy all the matlab folders to the top of the list.

Worked fine for me. You can try the function form if you want
clear('x', 'y');
clearvars('-except', 'z')
See if that works. I even tried it with cells and it worked. You don't have any functions called x, y, or z do you? They're variables, right?

Do
>> which -all strjoin
You should see
>> which -all strjoin
C:\Program Files\MATLAB\R2017b\toolbox\matlab\strfun\strjoin.m
Rename any other strjoin that you may have written so that it has a different name.
