Selecting a particular part of a string variable

Dear all,

I have

A={'BARI 500 esd' ...

'DUR NOR 18 df '

}

I want to choose the part of the string that is up to the number that appears in each string

That is, for the above example I want to select

'BARI 500'

'DUR NOR 18'

Is there a way to do that?

thanks

A = {'BARI 500 esd', ...
     'DUR NOR 18 df '};

B = cell(size(A));
for i = 1:numel(A)
  a     = A{i};
  index = find(isstrprop(a, 'digit'), 1);
  a     = a(1:index);
  index = find(~isspace(a), 1, 'last');  % hand coded STRTRIM
  B{i}  = a(1:index);
end

[EDITED] For your edited question:

 for i = 1:numel(A)
    a     = A{i};
    index = find(isstrprop(a, 'digit'), 1, 'last');
    B{i}  = a(1:index);
  end

Regular expressions might provide an easier way.

 fcn = @(s) regexpi(s, '^(\D+)', 'match', 'lineAnchors');  %regex function
 B = cellfun( fcn, A);    %run on cell array A
 B = strtrim(B);   %get rid of trailing spaces

@antonet: But this was what you were asking for. Please explain "I want to select" exactly.

 A={'BARI 500 esd' 'DUR NOR 18 df '};
a=char(A);
[n,m]=size(a);w=[];
for k=1:n
    v=[];testp=1;test=0;test2=0
    for h=1:m
        if length(regexp(a(k,h),'[0-9]'))>0
           test=1,testp=0,
        end
        if test==0 & testp==1  
            v=[v a(k,h)],test2=1
        elseif test==1 & test2==1
            v=[v a(k,h)],test=0
        else
            test2=0,testp=0,test=0

        end
    end
    w=strvcat(w,v);
end
disp(w)
