MATLAB: How do i create the following cell array

accessarraycellcreateindexmatrixvector

this is what I have in mind :

as you can see, the main matrix is 2*4, and within each cell there are 3 values

Question 1 :how do I create this ?

Question 2 if I want to access one of the cells( accessing all 3 values as a vector), corresponding to row r and column c , how can I do so ?

Quesiton 3 if I want to access the 2nd element of the 3rd top cells from the left ( here it would be 6 ), how can I do so ?

Q1.

C = {[2,3,1],[1,5,6],[4,6,5],[3,1,7];[3,5,7],[2,4,6],[2,6,3],[8,2,3]}

Q2.

C{r,c} % access the cell contents (i.e. the numeric array)
C(r,c) % access the cell itself

Q3.

C{1,3}(2)

You should also read the MATLAB documentation:

You can put cell arrays into any container variables, in particular:

Here are two cell arrays nested inside another cell array:

C{1} = {1,2,3};
C{2} = {'blue','anna'};

Note that cell arrays have two different kinds of indexing:

See the MATLAB documentation:

my_cell_array = {a,b,c};

Or if you are simply asking how to pre-allocate the cell array in advance:

my_cell_array = cell(1,3);
