How do I concatenate char and double classes?

I'm attempting to concatenate data of 2 different class types.
The first type is of Class char, with the size being 7 x 11.
z =
    DUE        
    DUE        
    BT    
    PRE_REL
    BT    
    BT    
    PRE_REL
The 2nd type is of Class double, with the size being 7 x 11.
y =
    58570                -1245.0111                -4807.8222
    58570                -1245.0111                -4807.8222
    58572                -1400.0111                -4950.8222
    58574                -1550.0111                -5000.8222
    58576                -1600.0111                -5150.8222
    58576                -1600.0111                -5150.8222
    58578                -1750.0111                -5200.8222
The desired output would be a single array that looks like this:
DUE                    58570                -1245.0111                -4807.8222
DUE                    58570                -1245.0111                -4807.8222
BT                     58572                -1400.0111                -4950.8222
PRE_REL                58574                -1550.0111                -5000.8222
BT                     58576                -1600.0111                -5150.8222
BT                     58576                -1600.0111                -5150.8222
PRE_REL                58578                -1750.0111                -5200.8222
In looking through the Programmer's Guide I'm not sure if I need to make a simple conversion or not. Any ideas would be helpful. Thanks.

        %Example
z =strvcat('DUE','DUE','BT','PRE_REL') 
data=rand(4,3)
%convert your char  array to cell array
c=cellstr(z)
%covert your double array to call array
n=num2cell(data)
out=[c n]

				You poor guy. You must be using an old version of MATLAB. The wonderful new table data type only came into being with R2013b. Please upgrade because like Mischa said, the table is the best way to go. Otherwise you'll be stuck using a cell array. Definitely more complicated to use. See the FAQ on cell arrays: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F to give you an idea of when you need to use parentheses and when you need to use braces . Actually I see Azzi and Jose-Luis already gave you code for that so just use that if you can't upgrade.
