matlab - white space in cell array -

i using textscan read text file , <55x1 cell> examples:

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

i want delete white spaces in each sting if have sting

 string = 'i 24 years    old'

and use

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

it eliminate spaces ,

 'iam24yearsold'

but cell doesn't work or don't know how how can that? suggestions please?

you can use strrep:

a = { 'aa aa'  'a  aaaa a'  'a =  aaaaa'  'aaaaaa'  ' a aaa'  'aa'  'aaa'  'aaaa'  'i 24 years    old'};  strrep(a, ' ', '')

this results in

ans =       'aaaaa'     'aaaaaa'     'a=aaaaa'     'aaaaaa'     'aaaaaa'     'aa'     'aaa'     'aaaa'     'iam24yearsold'
