MATLAB: How to choose randomly value from cell

cellcell arrays

>> SI

SI =

1×2 cell array

[1×2 double] [1×2 double]

>> for i=1:numel(SI)

disp(SI{i});

end

1 2

2 3

I want to choose value randomly from SI

for example the value is just one value among 1 2 like 1 or 2

Why not just,

a=cell2mat(SI);
b=a(randi(length(a)));%b is a random value inside all of SI

It's pretty easy really. Here an example:

A = {rand([2 1]),rand([5 1]),rand([3 1])};
B = {rand([10 1]),rand([12 1])};
C = [A B]; %adds cell B to A

To get the overall minima over a cell array without caring what the position is,

min( [YourArrayName{:}] )
