converting specific string variables to double

Dear all,

I have the following matrix

 A={'name'
   'afsaf'
   'sfsfs'
   '0'
 'rpytui'
'0'
'0'
'0'
'dfgl'
'trd'
};

I want to convert the zeros which are string variables to numeric variables; that is

 A={'name'
   'afsaf'
   'sfsfs'
   [0]
 'rpytui'
[0]
[0]
[0]
'dfgl'
'trd'
};

Is there a way of doing that?

Thanks in advance!

I knew there was an easier way:

A(ismember(A,'0'))={0}

This one is much faster

Answer 2

A(strcmp(A, '0')) = {0}

[Azzi Abdelmalek]

This is faster

A=repmat(A,100000,1);
tic
A(ismember(A,'0'))={0};
toc
tic
A(strcmp(A, '0')) = {0};
toc

Elapsed time is 0.047910 seconds.

I am quite sure there is a simpler way, but one way is

A(cellfun(@(x)isequal(x,'0'),A))={0};

Answer 4

A(~cellfun('isempty',strfind(A,'0')))={0}
