MATLAB: Concatenating an empty numeric array to a cell array

Question

Hi,

I need to add an empty numeric array at the end of a cell array mycellarray that contains numeric arrays. However when I execute : [mycellarray []] it does not concatenate the empty array to the end of mycellarray.

I find it curious since the same command works well with a non-empty array. It looks like matlab is treating [] as if it was {}…

For example :

mycellarray = {[1 2] [4 3 2]};
[mycellarray []]

gives {[1 2] [4 3 2]} as a result, instead of {[1 2] [4 3 2] []}, but :

 mycellarray = {[1 2] [4 3 2]};
 [mycellarray [3 4]]

returns {[1 2] [4 3 2] [3 4]} and not {[1 2] [4 3 2 3 4]}…

Can somebody help me with this ?

Answer 1

I am not sure why this is allowed:

[mycellarray [3 4]]

I think it should require

[mycellarray {[3 4]}]

which works for empty also

[mycellarray {[]}]
