join char/cell to double matrix

I have

c=['IBM';'SPY';'IVV'];
celldata=cellstr(c);

and

price= hist_stock_data(celldata');

I want a matrix as the following:

IBM     SPY    IVV

price1 price2 price3

How about constructing a cell array

for col = 1 : size(c, 1)
    % For each row in c
    % Extract row from character array and place into a cell.
    ca{col, 1} = c(col, :); % String goes into first row of cell array.
    % Stuff number into second row of this column:
    ca{col, 2} = price(col);
end

Or you could use a table variable instead of a cell array.

yes but the size of prices is 840,3, and not 1,3

Looks like you forgot to mention that at first so there's no way I could have known. So just add a loop to add rows

for col = 1 : size(c, 1)
    % For each row in c
    % Extract row from character array and place into a cell.
    ca{col, 1} = c(col, :); % String goes into first row of cell array.
    % Stuff number into rows of this column:
    for row = 1 : size(price, 1)
        ca{col, row+1} = price(row, col);
    end
end

Since you're not yet familiar with for loops and the size function (or else you would not have asked me), you should probably look up information on the for loop and the size function in the help documentation, since it's pretty basic yet crucial to know.

Actually, you'd better study up on cell arrays in the FAQ also: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F because they're far trickier than for loops.
