Matlab: adding cell to cell array

Question

Suppose I have a 3x1 cell array:

c = {[1, 2, 3]; [1, 2, 3, 4, 5]; [1, 2]}

I now want to add another array, to make it a 4x1 array. How do I do this? I have tried the following:

c = {c; [1, 2, 3, 4]}

But it then tells me that:

c = {3x1 cell}    [1x3 double]

Whereas I want:

c = {4x1 cell}

What should I do? Thanks.

c=[c; [1, 2, 3, 4]]

or

c{end+1}= [1, 2, 3, 4]

Thanks. In the first of your examples, why is the syntax to use a square bracket rather than a curly bracket for the outer bracket? I thought the square bracket would be just for adding an element to a regular array.

[x,y] is the syntax to concatenate. [1,2,3,4] concatenates four doubles to a vector. [{1},{1},{1},{1}] concatenates four cells to one cell. If mixed, it's implicit a cell: [{1},{1},1,1].

To complete the lesson: c(end+1)= {[1, 2, 3, 4]};. No better, but hopefully helps demonstrate MATLAB syntax a bit.
