Moving-block bootstrap
[ovb,selb,k,re]=movblockboot(T,l,B)
T = sample size
l = block length
B = number of bootstrap replications
ovb = (l x T/l) matrix that decomposes the initial sample into l overlapping blocks
selb = (T/l x B) matrix that randomly selects the overlapping blocks
k = number of blocks
re = size of the last block if T/l not an integer
