how can I choose random "n" matrices from array of matrices ?

Dear all,

I have a problem and I hope somebody can help.

I have vector array of elements, the array contains matrices and I want to choose randomly "n" matrices from array

how can I choose ???

m1=[ 0 1; 0 0];
m2=[ 0 1; 0 1];
m3=[ 1 1; 0 0];
m4=[ 1 1; 0 1];
array=[m1 m2 m3 m4];

I hope I am clear enough.

Thanks in advance,

Ghaida

If you followed the advice I gave in response to your last question:

https://www.mathworks.com/matlabcentral/answers/441492-how-to-get-the-first-position-in-the-array-and-get-size-array-contains-matrices#answer_358027

then this would be trivial:

N = number of matrices you want to get
idx = randi(numel(C),1,N);
C(idx)
