Scramble words in MATLAB.

hi my friends. im looking for if there is any way to scramble word in MATLAb. exactly i want that a function returns a string containing the words in the original string in random order and also i wannaa use randperm to do tthat. i wrote this function but i was not succesful.

function [sout] = scrambleWords(s)
%for Non-Functional use%
%s = input('Enter a few Words:\n','s');

cutPoints = regexp(s,'\s{1,}'); % for More than 1 Space=>  '\s{2,}'
sout =  mat2cell(s,1,diff([0 cutPoints numel(s)]));
sout =  randperm(sout,10,3);

end

See below:

function [permsout] = scrambleWords(s)
   cutPoints = regexp(s,'\s{1,}'); % for More than 1 Space=>  '\s{2,}'
   sout      = mat2cell(s,1,diff([0 cutPoints numel(s)]));
   perm      = randperm(length(sout));
   permsout  = sout(perm);
end

As a last step you could convert the cell array back to a string and return by the function.

Hi Mr Kim. i tried ur code but it does not get in random order. it was the result:

>> scrambleWords('String to Randperm')

sout = 

      'String '    'to '    'Randperm'

perm =

       1     2     3

permsout = 

    'String '    'to '    'Randperm'

ans =

    'String '    'to '    'Randperm'

You are probably still working with some old code. Copy and paste the function in my answer and save under a new function name. This is what I get:

>> scrambleWords('this should really work')
ans = 
    'work'    'should '    'this '    'really '
>> scrambleWords('this should really work')
ans = 
    'should '    'really '    'this '    'work'
  >> scrambleWords('this should really work')
ans = 
    'should '    'this '    'really '    'work'
