using regexp for char data

out1 =

p.11 109 820 109

p.12 503 159 117

p.13 234 207 151

p.14 139 134 215

Name Size Bytes Class Attributes

 out1           1x188              376  char      global

%when I want to exctract first column of this data I use

out1 = char(regexp(out1,'p\.\d+','match'))

%the problem is first column characters varies. for example out1 would be;

out1 =

o10 109 820 109

o12 503 159 117

o13 234 207 151

o14 139 134 215

%or it would be

out1 =

oa10 109 820 109

ob12 503 159 117

oc13 234 207 151

od14 139 134 215

%as you seen, it changes so I need to use regexp without dependent first character or numbers belongs to first column.

thanks in advance

a=cellfun(@(x) regexp(x,'\d+','match'),out1,'un',0);
for k=1:numel(a)
  out(k,1)=str2num(char(a{k}(1)))
end

[sermet]

it doesnt't work I give you initial codes;

cellArray=cellstr(cellArray)
out1 = sprintf('%s\n', cellArray{:})
a=cellfun(@(x) regexp(x,'\d+','match'),out1,'un',0)
for k=1:numel(a)
out(k,1)=str2num(char(a{k}(1)))
end

%it gives 
Error using cellfun
Input #2 expected to be a cell array, was char instead.

It seems like out1 is a string, which contain line breaks: "1x188 char". Do you assume it is a cell string.

yes I do
