error when using clearvars

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?

[Alberto]

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?

Hello, im having the same issue, how i choose the correct strjoin?

[Image Analyst]

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.
