Hello here is my string :
'abc "abc" '
I need to throw out single quotation mark and replace double quotation mark to single quotation mark so the output will be :
abc 'abc'
How to do it ?
Thanks a lot.

What does "here is my string" exactly mean? Strings do not contain the surrounding quotes. They appear only, if e.g. a cell string is printed to the command window:
C = {'string'};
disp(C)
Therefore I assume this is enough:
S = 'abc "abc" ';
S = strrep(S, '"', char(39));
fprintf('%s\n', S);
I use char(39) because it looks less strange than '''', but both create exactly the same: one quote character.

I need to delete this quotes because I use later this into function find.
find(S)
when I use it the problem is that it doesn't work as it should. The function work fine when I put this statement without quotes.

@Jonasz: It is not clear, if your string is:
S = 'abc "abc" '
or
S = '''abc "abc" '''
Please clarify this at first.

doc strrep
Here it is:
str = '''abc "abc" '''
str2 = strrep(strrep(str,'''',''),'"','''')
