Dynamic sampling

The block performs sampling of an element from the vector by the set number. Operation algorithm of the block:

where u₁(t) is the first input scalar signal determining the number of the selected element, starting from 1; u_2,i(t) is the i-th element of the second input vector signal u₂(t) from which sampling is carried out; n≥1 is the dimension of the second input, a natural number.
