How to remove single quotes using regexprep

I would like to know how can we eliminate the single quotes in a cell using regexprep. I have a 1x150000 cell array.

I tried using three single quotes ''', its giving me an error.

Are you sure it's not just the visualization effect when you try to display a cell array of string on the command window.

Ex: a = {'hi'}

[vish]

ohh. Now I know what you mean. I am getting the single quotes only for few elements. Rest of them are as I desire.

Then Andrew's code should work fine.

STRREP is easier than REGEXPREP and needs the half processing time:

D = strrep(C, '''', '');

If the worm of quotes looks ugly, use:

D = strrep(C, char(39), '');

[David Young]

Yes, strrep is far faster than regexprep on my test. How disappointing that regexprep doesn't recognise that it has this simple case and process it as fast as strrep does.

Answer 2

[David Young]

The solution using regexprep is just

D = regexprep(C, '''', '');

Answer 3

[Lakhan]

its not working in my case

if true
  % code
>> a = {'hi'}

a =

    'hi'

>> D = strrep(a, '''', '')

D =

    'hi'
  end

Your string does not contain quotation marks. You have created a cell array, and string elements of a cell array are displayed surrounded by quote marks. Look at

a{1}
