A rectangular signal with variable width and distance is generated and analysed (see figure). Every sample has dimension n=500. In the example N samples are generated, that only differ by the two parameters width and distance. As a result it can be seen that the data can be embedded from a 500- into a 2-dimensional space which's limits are specified by the limits of the two parameters.
Usage
lle_rectangular(N = 40, k = 5, v = 0.9)
Arguments
