Tmatrix is a cell array. So Tmatrix(1) is a cell. And Tmaxtrix{1} is a logical array. Since Tmatrix{1} is not a cell, you can't pass it in to cell2mat(), which expects a cell or cell array. To fix, use one of these lines of code:
X = cell2mat(Tmatrix(1)); % Uses parentheses
or
X = Tmatrix{1}; % Uses braces
X will be a logical matrix if you use either of those. Next, please read the FAQ to get a better intuitive feeling for what a cell array is and how to reference it: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F It will also show you when to use parentheses and when to use braces (which was the cause of your problem).
