Error in Y label

can anyone help out with 'error in y label', please? This normally happens when I copy the same codes from my desktop to my laptop with same version of MATLAB.

Does the error message say anything about invalid interpreter syntax?

Does your program have any non-English characters such as å or ñ in it?

Does your desktop and laptop have different Locale set up?

Many thanks Walter for your response.

1, No, there is no invalid int. syntax

2. No non-English Xter.

3. Same local set up.

Many thanks

Could you show us a ylabel-call that generates the error?

[Tino]

The call was: ”ylabel('Amplitude');”

[Tino]

Please find the error attached

That is odd. labelcheck() has existed at the same location since at least R2016b .

which -all labelcheck
ls(fullfile(matlabroot, 'toolbox', 'matlab', 'graph2d', 'private', 'labelcheck.m'))
