get the table from uitable into a matrix A

tableData = get(handles.uitable1, 'Data')
tableData = 
  '99'    [41]
  '77'    [13]

can i convert it to a normal matrix so i can do a function on it

Have you tried table2array?

[Guillaume]

table2array has nothing to do with uitable. It certainly won't know what to do with a cell array.

[Pawel Jastrzebski]

If I understood the code correctly:

tableData % returns a cell

Having recreated this cell, array2table seem to covert the cell to the table:

 a = {'99' '77'}            % cell
 b = [41 13]                % double
 b = num2cell(b)            % double to cell

 tableData = [a' b']        % cell concatenation

 t = array2table(tableData) % cell to table

The output:

t =

    2×2 table

      tableData1    tableData2
      __________    __________

      '99'          [41]      
      '77'          [13]

However, like you said, it doesn't make any sense to have the number stored as a char in the first place.

[Walter Roberson]

Do you want the '99' to be converted to numeric so that you end up with a purely numeric array?

[Amjad Green]

yes,the user inputs a matrix and i want to save in a matrix A so i can do my functions on it

Answer 1

[Guillaume]

Your uitable returns a cell array because you've defined the first column as char. If your uitable is supposed to contain numbers only then the easiest way to fix your problem, is to change the ColumnFormat of that first column to 'numeric'. If you show us the line(s) where you create that uitable we can give you the exact syntax.

Alternatively, it can be fixed after the fact, but it'll be slower and kind of pointless:

tableData = get(handles.uitable1, 'Data');
tableData = [str2double(tableData(:, 1)), cell2mat(tableData(:, 2))];
