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'

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
