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.

You need to escape the apostrophe by using it twice:
>> '''hello'''
ans = 'hello'
>> sprintf('''%s''','hello')
ans = 'hello'
This is explained in the documentation:

Thanks a lot that worked well. However from your Answer, i also figured this one out
s='''';
strcat(s,'hello',s)
>> 'hello'
typing four times Apostrophe.

There's mainly only two schools in how you introduce delimiter characters in strings:
  • double the delimiter. This is the way used by matlab, VB, and ?
  • use an escape character (usually \). This is used by pretty much all the other languages, C languages, Java, Python, PHP, etc.
