white space in cell array

I am using textscan to read text file and I get <55x1 cell> examples:

 'aa a aa'
 'a  aaaa a'
 'a =  aaaaa'
 'aaaaaa'
 ' a a a aaa'
 'aa'
 'aaa'
 'aaaa'
  .
  . 
  .
  .

I want to delete the white spaces in each sting If I have a sting 

 string = 'I am 24 Years    old'

And I use 

  string(ismember(string,' ')) = [];

it will eliminate the spaces and I will get 

 'Iam24Yearsold'

But with the cell doesn't work or I don't know how to do it How can I do that? any suggestions please?

Solution

  • You can use strrep: 

    a = { 'aa a aa'
 'a  aaaa a'
 'a =  aaaaa'
 'aaaaaa'
 ' a a a aaa'
 'aa'
 'aaa'
 'aaaa'
 'I am 24 Years    old'};

strrep(a, ' ', '')

    This results in

    ans = 

    'aaaaa'
    'aaaaaa'
    'a=aaaaa'
    'aaaaaa'
    'aaaaaa'
    'aa'
    'aaa'
    'aaaa'
    'Iam24Yearsold'
