I have N groups of arrays. Each group contains 3 arrays for example.
Now I would like to take only one array at random from each of these groups and take a product with B array.
For example:
Group_1=[A_1 ,A_2, A_3];
...
Group_N=[A_m ,A_k, A_l];
Now I am choosing one array in each group and taking a product with B
C_1=A_2*B; % Matlab has choosen random A_2 in group_1
...
C_N=A_k*B; % Matlab has choosen random A_kin group_N
How to implement such computation?
I have tried A(randi(numel(A))), but it doesn't work.
