random resampling with rebalancement

I have an array Y (3000*1) from which i want to drow an n=100 random samples with rebalancement(with repeating possible), such that each sample contains 252 consecutive values from Y (i.e only the starting point is randomly chosen) the reslut dimensions are meant to be 252*100

Thank you for helping with this

what if I pick the 2999 value? Should I continue in a circular way, i.e.

2999, 3000, 1, 2 ...

No, they have to be 252 consecutive values; so the last 251 values of Y must be exonerated from the choice of the random starting point.

thank you

r = randi(2748,100,1);
x = zeros(252,100);
for k = 1:100
x(:,k) = Y(r(k):r(k) + 251);
end

Thank you for your answer It works well
