could "cellfun" solve my problem?

% Line Data for B-Bus (Shunt Admittance)Formation.

% function bbus = bbusppg,8     % Returns B-bus..
linedata = linedatas ,8;
fb = linedata(:,1);
tb = linedata(:,3);
b = linedata(:,7);
nbus = max(max(fb),max(tb));    % no. of buses...
nbranch = length(fb);           % no. of branches...
bbus = zeros(nbus,nbus);
 for k=1:nbranch
     bbus(fb(k),tb(k)) = b(k);
     bbus(tb(k),fb(k)) = bbus(fb(k),tb(k));
 end

i got:

linedata = 

      [1]    '1a'    [3]    '2a'    [0.0024]    [0.0183]    [0.0264]    [1]
      [2]    '1b'    [7]    '4a'    [0.0540]    [0.2230]    [0.0246]    [1]
      [4]    '2b'    [5]    '3a'    [0.0470]    [0.1980]    [0.0219]    [1]
      [6]    '3b'    [1]    '1a'    [0.0346]    [0.1055]    [0.0215]    [1]
      [4]    '2b'    [8]    '4b'    [0.0024]    [0.0173]    [0.0345]    [1]

Undefined function 'max' for input arguments of type 'cell'.

Error in bbusppg (line 9)
nbus = max(max(fb),max(tb));    % no. of buses...

if I apply "cellfun' is it work?could I apply this for columns 1,3&7 only .if yes,how? and if the answer No what can i do?!

You just need to convert your numeric data from cell arrays to a numeric arrays:

fb = cell2mat(linedata(:,1)); 
tb = cell2mat(linedata(:,3));

etc...

thanks,I'll try that

can't thank you enough, I tried it and it worked :D
