MATLAB: How o add apostrophe (‘) in a char or string array

Question

I'm using SIMULINK, in the mask of the block I have created a button that opens a dialog box searches for file using 'uigetfile' in return I get [filename] which is character. I want to display that [filename] as 'filename' with apostrophes in an Edit Box parameter. So that my code can pick 'filename' as string value.

Answer 1

You need to escape the apostrophe by using it twice:

>> '''hello'''
ans = 'hello'
>> sprintf('''%s''','hello')
ans = 'hello'

This is explained in the documentation:
