>> a={[1 2 3],[2 3 4;1 2 3]}
a = 
    [1x3 double]    [2x3 double]
>> vertcat(a{:})
ans =
     1     2     3
     2     3     4
     1     2     3

Hi Song,

You can use 'cat' command to concatenate array according to your need.

 m = cat(1,a{1},a{2})

Above command will concatenate the array 'a' along vertical direction as you need.
