Dear All, If I have points (x,y) In space such as:
x=[ 5 5 5 13 12 13 28 21 25 31 39 39 45 41 49 ];
y=[ 9 25 48 4 19 39 37 45 50 9 2 16 22 30 31 ];
what is the best way to generate random matrix in this space
[(x11 ,y11), (x12 ,y12), (x13 ,y13),…;
(x21 ,y21), (x22 ,y22), (x23 ,y23),…;
(x31 ,y31), (x32 ,y32), (x33 ,y33),…];

The result does not have valid Matlab syntax. Therefore we cannot guess reliably, what this should mean. Please edit your question to clarify it.

I am not 100% sure I understand what you mean, but this may help you get started:
x=[ 5 5 5 13 12 13 28 21 25 31 39 39 45 41 49 ];
y=[ 9 25 48 4 19 39 37 45 50 9 2 16 22 30 31 ];
N = numel(x);
idx = randi(N,3);
Mx = x(idx);
My = y(idx);

I don't know why you are calling (x,y) point in space?
n=50;
M=cell(3,4)
out=cellfun(@(x) randi(n,1,2),M,'un',0)
celldisp(out)
