how to fetch data from table?

hello, i want to fetch data from two tables. i created the tables but i dont know how to fetch the datas.

function [z] = pushbutton1_Callback(hObject, eventdata, handles)
global nbb
global ntl
global ngn
global t1
a=findobj(gcbf,'TAG','edit1'); % bus say?s? girdigimiz text'i a'ya atad?k.
b=findobj(gcbf,'TAG','edit2'); % hat sayisi girdigimiz text'i b'ye atad?k.
c=findobj(gcbf,'TAG','edit3'); % jeneratör say?s? girdigimiz text'i c'ye atad?k.
bs=get(a,'string');
hs=get(b,'string');
gs=get(c,'string');
nbb=str2num(bs)
ntl=str2num(hs)
ngn=str2num(gs)

      data = zeros(nbb,12);
      edit=true(1:nbb);
      colnames = {'BUS NO', 'BUS CODE','VOLTAGE MAG.','ANGLE DEG.','LOAD(MW)','LOAD(MVAR)','GEN(MW)','GEN(MVAR)', 'GEN Qmin','GEN Qmax','SHUNT RES.','SHUNT REAC'};
      t1 = uitable('Data', data, 'ColumnName', colnames, 'ColumnEditable',edit, ...
                'Position', [100 240 720 100])
      linedata = zeros(ntl,6);
      editbir=true(1:ntl);
      colnames = {'SEND', 'RECEIVE','RESIS','REAC','COND','SUSCEP'};
      t2 = uitable('Data', linedata, 'ColumnName', colnames, 'ColumnEditable',editbir, ...
                'Position', [100 100 500 100]);

Answer 1

thanks a lot. but i solved the problem by using uitable from guide. but now i have another problem. i get matris from table using cell2mat function.

H = cell2mat(get(handles.uitable3,'Data')); i use the matris as an input at another function and i get this error.

Undefined function or method 'H' for input arguments of type 'double'.

[Walter Roberson]

Are you retrieving H in one routine and using it in a different routine? That will not usually work. See the FAQ on alteratives,

i can't fetch double from cell. i have a problem with cell2mat function.

>> X={'1.2'};

>> y=cell2mat(X)

y =

1.2

>> size(y)

ans =

1 3

>> y(1,1)

ans =

1

[Walter Roberson]

y = str2double(X{1});

[Elif]

is there another way for it? if the cell dimension increase str2double does not work.

[Walter Roberson]

str2num()

Answer 2

[Walter Roberson]

data1 = get(t1,'Value');

Then use cell array indexing to access the elements.

thanks for everything.
