Can't open *.m files

Hello, I'm using MATLAB R2020b and there's a problem while opening *.m files.

The error message says:

'unarginchk' is an unrecognized function or variable.

Error occurred: onCleanup (line 52)

unarginchk(1,1);

Error occurred: getnicedialoglocation (line 23)

c = onCleanup(@() close(convertData.hFig));

Error occurred: msgbox (line 332)

DefFigPos = getnicedialoglocation(DefFigPos, get(figureHandle, 'Units'));

Error occurred: errordlg (line 59)

handle = msgbox(ErrorStringCell, dlgName, 'error', replace);

Error occurred: uiopen (line 185)

errordlg(err);

I believe the function name is changed unintentionally. It's supposed to be narginchk not unarginchk.

which -all narginchk

built-in (/MATLAB/toolbox/matlab/lang/narginchk)

which -all unarginchk

'unarginchk' not found.

Below is how line 52 of onCleanup.m is supposed to be in MATLAB R2020b.

Hello Regina,

I understand you are facing a problem while opening ".m" files in MATLAB R2020b. Without access to the source code, pinpointing the exact solution to your query is challenging. However, based on the error message you've shared, I can offer some guidance on addressing the "Undefined function or variable 'x'" issue. Please refer to the documentation below, which outlines some possible solutions for this error:

Hope this helps.
