How to insert the missing number into the cell array?

Suppose that I have this

I=[3 5 6 8 10 11]
A={[3];[6;8];[];[11]}

How to find the missing number of I in A and insert that number into any position of A? for intance like:

A={[3];[6;8];[5];[10;11]}

YOu have I in hand always?

[Hang Vu]

yes I have I in hand, it would be changed depend on my input.

One quick question:

How did you define the position of '10' in your cell array A?

[Hang Vu]

It will be random sir. That is just my example, I want to randomly insert the missing numbers into A, not only the empty cell

Answer 1

I=[3 5 6 8 10 11] ;
A={[3];[6;8];[];[11]} ; 
% get empty cell
idx = cellfun(@isempty,A) ; 
A{idx} = setdiff(I,cell2mat(A))

[Hang Vu]

Thank you, but I want to insert in any position not only the empty cell. and it's should display as 1 column. Yours is 1x2

A =

  4×1 cell array

    {[       3]}
    {2×1 double}
    {1×2 double}
    {[      11]}

I inserted in the empty cell, the elements left in I. YOu can use the following:

A{1}(end+1) = 5 ;  % this will insert in first cell in second position 

[Hang Vu]

Thank you for your time! But with that way it is just manually input

[KSSV]

Then how you want?

[Hang Vu]

Because I have here are 2 missing numbers, and I don't know these two, How can I use

A{1}(end+1) = 5 ;

[KSSV]

I have showed you how to get missing numbers already. :

miss = setdiff(I,cell2mat(A))

[Hang Vu]

this setdiff found 2 numbers but the A{1}(end+1) is only 1 position, so it doesn't work. And do you have any way to ramdom insert instead of typing the position?

[KSSV]

idx = randsample(length(A),1)

[Hang Vu]

Thank you, but Do you get my point? I already tried this

I=[3 5 6 8 10 11] ;
A={[3];[6; 8];[];[11]} ; 
% get empty cell
idx = randi(size(A,1))
A{idx}= setdiff(I,cell2mat(A))

Could you please make this with your way?

A={[3];[6;8];[5];[10;11]}

[KSSV]

I=[3 5 6 8 10 11] ;
A={[3];[6;8];[];[11]} ; 
% get empty cell
idx = cellfun(@isempty,A) ; 
missing = setdiff(I,cell2mat(A)) ; 
A{idx} = missing(1)

Thank you so much! I modified a bit and it worked.
