How do I generate 1000 random rows from an array only once, so that if I run the program again, it will still be the same set of randomly generated number previously

2 views (last 30 days)
% Generate a matrix named foo
foo = randn(10000,2);
% draw 1000 random samples
index = randsample(1:length(foo), 1000);
bar = foo(index,:);
Suppose I have the code above, I only want to generate 1000 random rows once. I do not want a different set of 1000 random row everytime I run the program again. Please help. Thank you
