Question

MATLAB CODE ONLY

How can I write a program that repeats all spaces and all punctuation marks in a string?
For example if I had a statement like: 'hello humans!'

It would turn into: 'hello__humans!!'

Or if I had a statement like: 'I ride bikes.'

It would turn into: 'I__ ride__bikes..'

Show the code and outputs pls.

Thanks

Here is a Matlab function that does the above task:

% function to repeat punctuations

function s = repeat_pun(str)

   new_str = ""; % initialize empty string

   n = length(str); % lenght of original string

  

   for i = 1:n % loop through characters of original string

       new_str = strcat(new_str, {str(i)}); % concat char to new string

       if isstrprop(str(i), 'alphanum') == 0 % if char is not alphanum

           new_str = strcat(new_str, {str(i)}); % concat again to new string

       end

   end

   s = new_str; % return new string

end
