I have a table with string of values in columns.
T1 =
5×1 table
A
___________________________________________________________________________________
{'[28.346853874154966, 284.04836936606813, 57.820072802912115, 64.72700622938805]'}
{'[16.520020800832032, 120.07328691828508, 57.82007280291212, 46.34078417002567]' }
{0×0 char }
{0×0 char }
{0×0 char }
When i am using this code T1.(1) = str2double(T1{:,1}); I am getting NaN values. in table.
T1 =
5×1 table
A
________

It would be easier for us to make sure suggested code works as you expect if you uploaded the table T1 in a *.mat file, using the paperclip icon in the INSERT section of the toolbar.

% My best guess at your data
A = {'[28.346853874154966, 284.04836936606813, 57.820072802912115, 64.72700622938805]';
'[16.520020800832032, 120.07328691828508, 57.82007280291212, 46.34078417002567]';
'';
'';
''};
T1 = table(A);
% Convert to a cell array of doubles
M = cellfun(@str2num,T1.A,'UniformOutput',false)
