MATLAB: Putting quotes around the value of the variable

Question

Hello I have a question regarding quotes, I have looked at other posts, but they do not match the question I have.

If I have a variable x = this_test_string

I would like to put a quote around this_test_string so it looks like the following 'this_test_string'

In my code, I don't know what x will be beforehand so I must have,

' (value of x) '

Is there a way to do this?

''' x ''' and '' x '' did not work.

Thanks

Worked with [ '''' x '''']
