String array and Numeric values

Hi,,

I have a String array that contains Names, I want to allow the user to choose a Name to change either by writing the name as a string OR by writing it's index as a number..

So I wrote this code, but it seems faulty.. Can anyone help with this..

Thanks in advance:

    clear all
  clc

Nums=[1:5]
%NumsStr=num2str(Nums)

for i=1:5
    s=input('s= ','s')
    s=strtrim(s);
    S{i}=(s);
    clc
end

S
for i=1:5
    tst=input('edit what ','s')
    try
        res=strmatch(tst,S,'exact')
        if((length(res)~=0) && (length(res)<2))
            S{res(1)}=input('TEXT_MODE, New String =','s')
        else
            %NumRes=strmatch(tst,num2str(Nums))
            NumRes=find(Nums==tst)
            if((length(NumRes)~=0) && (length(NumRes)<2))
                S{NumRes(1)}=input('NUMBER_MODE, New String = ','s')
            end
        end
    catch ME

      end
  end

In your original code, you should change the line after the else statement to:

NumRes=find(Nums==str2num(tst))

I believe this solved the problem.

So many thanks.

% Say your String cell looks like this:
S = {'Ted' 'Jim' 'Nancy'}

% To change by name:
cname = 'ted';  % User wants to change 'Ted'...
cname_new = 'Frank';  % to 'Frank'.
idx = strcmpi(S,cname);  % Find 'Ted'
if any(idx)
    S{idx} = cname_new; % Change to 'Frank'
end

Now to use an index instead of a name, just let the user enter cname_new and idx.

EDIT In response to your comment:

for ii =1:5
    s = input('s= ','s');
    S{ii}=strtrim(s);
    clc
end
S

for ii = 1:5
    tst = input('Edit what string in array? ','s');
    idx = strcmpi(S,tst);

      if any(idx)
          T = input('TEXT_MODE, Enter New String: ','s');
          S{idx} = T;
      else
          idx = str2double(tst);
          if ~isnan(idx)
              T = input('NUMERIC_MODE, Enter New String: ','s');
              S{idx} = T;
          end   
      end
  end
  S
