Matlab error: readonly workspacefunc 350

Hi, We're having a problem with a Matlab error in Matlab 2017a. Whenever we try to view a variable in the workspace, by double clicking on the variable in the Workspace panel, it opens the variable in a new window and displays an error message. The error message is entitled 'Variables' and reads 'readonly Error: Unexpected MATLAB expression. workspacefunc 350'. I can't interact with the variable window until I select ok. It also occurs when I open any variables within variables and periodically reappears if you leave variables open. Does anyone know how to solve this? Thanks.

This error is usually caused by having user-defined functions by the name "builtin", "strjoin" or "strsplit".

If that is the case, these functions shadow built-in MATLAB functions resulting in this error. Try executing:

which -all builtin
which -all strjoin
which -all strsplit

to see if there are any user defined functions by this name. Renaming the user defined functions by these names should resolve the issue.

Also, refer to the below MATLAB Answers link which talks about a similar issue:
