I am trying to convert this column of characters:
'D48-J06-W470'
into a cell so I can append to a matrix.
I have used str2double but I keep getting errors.
I have searched online but nothing useful arose.

Hi!
It seems you want to do:
ListCell = num2cell(List);
NewCol = size(List, 2) + 1;
for n = 1:size(Table, 1)
tf = (List(:, 1) == Table{n, 1});
ListCell(tf, NewCol) = Table(n, 3);
end

s='D48-J06-W470'

List(:,1) is an array of ID's. Table(:,1) are the ID's associated with the actual label. The idea was to assign a label in List as the 8th column.
I have been told that this is not possible because the matrix cannot not take more than one character, is this true? I may have to think of something else.

Can you be more specific, the below converts it to a cell array:
S = 'D48-J06-W470';
S = {S};
How are you using the term "cell" here?

The table was retrieved from a MS Access file. That's correct, Table is a cell.
I want to take the third column of Table, and append to a 40 x 4 matrix of type double using the ID in column 1. I have done this part, I just need to deal with the data types. I cannot simply use mat2cell as I get this error:
Warning: Single input behavior is obsolete and will be removed in a future release of MATLAB. Use
C={X} instead.

In @(hObject,eventdata)script('menu_loadFile_Callback',hObject,eventdata,guidata(hObject))
nor can I use {matrix}

I tried using:
cellfun(@(c_) c_ - '0', Table(index,3), 'UniformOutput', false);
but
The following error occurred converting from cell to double:
Error using double
Conversion to double from cell is not possible.

Try this to concatenate cells to make a cell array:
% Create 3 sample strings (character arrays).
string1 = 'D48-J06-W470'
string2 = 'D50-J07-IA2'
string3 = 'abcdef-123456789'
% Make the first cell:
ca = {string1};
% Append strings 2 and 3 into additional cells
% so that we will have a cell array.
% We can use either of 2 different methods (or more).
ca{2} = string2; % Method #1
ca(3) = {string3}; % Method #2
% You can do it via either method.
% Display the cell array.
celldisp(ca);
Be sure to check out the FAQ http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F for a good explanation of what they are, how they work, and how to use them.
